DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

allele for a given SNP (which can vary between populations particularly for highlypolymorphic SNPs)

The defining variant for a given DME gene star allele may be the only variant neededto identify that particular star allele The defining allele is sometimes referred to as thePrimetag SNPPrime Common allele names are provided for many DME variants in the PGxCommon Markers file See ldquoThe PGx Common Markers fileldquo on page 26

The DME Assay collection variants have been mapped for the genes having publicallele nomenclature sites This allele nomenclature is searchable on the DME assayproduct pages and in the downloadable TaqManreg Drug Metabolism GenotypingAssays Index file available at wwwthermofishercompgx The public allelenomenclature websites provide information on DME gene star allele haplotypes thedefining polymorphisms for these alleles and links to the NCBI dbSNP website forvariants having an reference SNP (refSNP) identifier or rs ID

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

The VICtrade dye probe is associated with the C allele and the FAMtrade dye probe isassociated with the T allele

In this example the SNP alleles (CT) are the reverse complement of those given in thestar allele nomenclature CYP2D64 g1846GgtA This is because the context sequencealleles are provided in the (+) reference genome strand orientation whereas the starallele nucleotide changes are provided with respect to the CYP2D6 gene referencesequence that maps to the (ndash ) genome strand

Several important DME gene variants are triallelic SNPs wherein 3 bases occur at thesame genomic location Triallelic SNP targets can be interrogated using a pair ofTaqManreg assays Each assay contains one probe for the major SNP allele which islabeled with the same reporter dye (VICtrade dye) in both assays and one probe for oneof the minor alleles which is labeled with the second reporter dye (FAMtrade dye) Togenerate accurate sample genotypes the two assays must be run independently onthe same panel of samples and the resulting allelic discrimination plots must beanalyzed in concert comparing the genotype cluster positions from both assays to amap of the true sample genotypes See Table 15 on page ldquoAnalysis guidelines SNPgenotyping assays for triallelic SNPsldquo on page 61 for analysis

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

Assay sets to two highly studied SNPs that have an adjacent less frequently detectedSNPs are available In each case the minor alleles of each SNP are not found togetherin the same haplotype

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

See The Human Cytochrome P450 (CYP) Allele Nomenclature Database CYP2D6 webpage (wwwcypalleleskisecyp2d6htm) or the PharmGKB web page(wwwpharmgkborg) plus associated references for more details about these alleles

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

At least two assays are required to detect copy number variation in CYP2A6bull The CYP2A6 intron 7 assay can be used to detect 4 deletion and 1 duplication

alleles This assay will amplify both full length CYP2A6 and the partially activeCYP2A6CYP2A7 hybrid allele CYP2A612 but will not be able to discern them

bull The intron 1 assay can also be used to detect 4 deletion and 1 duplicationalleles This assay will amplify full length CYP2A6 but will not be able to amplifythe CYP2A612 hybrid allele

bull If both CYP2A6 assays are run samples containing 12 alleles can bedistinguished from those containing full‑length alleles For example a 112sample will give 2 copies using the intron 7 assay and 1 copy using the intron 1assay whereas a 11 sample will give 2 copies with both assays

Additionally CYP2A7 assays can be used to corroborate the presence of CYP2A612alleles The CYP2A7 exon 1 assay will amplify the hybrid CYP2A612 allele whereasthe intron 7 assay will not amplify intact CYP2A6 or the CYP2A612 allele

Isolate DNA from buccal swabs

This section contains brief procedures For detailed information refer to MagMAXtrade

DNA Multi-Sample Ultra Kit (human buccal swabs) User Guide (Pub No MAN0010293)

Refer to Best Practices for Collection of Buccal Swabs Quick Reference (GenotypingExperiments) (Pub No MAN0014348) for sample collection instructions

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Prepare the Wash Solutions from the concentratesbull Add 25 mL of isopropanol to Wash Solution 1 Concentrate mix and store at

room temperaturebull Add 132 mL of ethanol to Wash Solution 2 Concentrate mix and store at room

temperature

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Genotyper Software) to make distinct genotype calls for assays with merging clusters(see example below) In these cases use the real‑time traces from the QuantStudiotrade

Expected versus unexpected noamp and undetermined calls

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

Good PCR practice

Prevent contamination and non-specific amplification

PCR assays require special laboratory practices to avoid false positive amplificationsThe high throughput and repetition of these assays can lead to amplification of oneDNA molecule

PCR good laboratory practices

When preparing samples for PCR amplificationbull Use a positive‑displacement pipette or aerosol‑resistant pipette tipsbull Follow proper pipette‐dispensing techniques to prevent aerosolsbull Wear clean gloves and a clean lab coat (not previously worn while handlingamplified PCR products or used during sample preparation)

bull Change gloves whenever you suspect that they are contaminatedbull Maintain separate areas and dedicated equipment and supplies for

ndash Sample preparationndash PCR setupndash PCR amplificationndash Analysis of PCR products

bull Do not bring amplified PCR products into the PCR setup areabull Open and close all sample tubes carefully Centrifuge tubes before opening

Avoid splashing or spraying PCR samplesbull Keep reactions and components capped as much as possiblebull Clean lab benches and equipment periodically with 10 bleach solution Use

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

Gender‐specific assays in PGx studies can aid sample tracking The TaqManreg SNPGenotyping Assay C_990000001_10 targets a gender‐specific polymorphic region inthe amelogenin gene that is commonly used in forensic sex determination tests TheVICtrade dye probe detects a 6 base deletion which occurs in the X‐specific amelogeningene whereas the FAMtrade dye probe detects Y‑chromosome sequences In genotypingexperiments male samples run in the heterozygous cluster position and femalesamples run in the VICtrade homozygote cluster Some males lack the Y‐specificamelogenin gene and will type as female Run the C_990000001_10 assay incombination with a Y‑chromosome assay to identify any mistyped samples For moreinformation go to wwwcstlnistgovstrbaseAmelogeninhtm

The PGx Common Markers file (wwwthermofishercompgx) contains a list ofcommonly requested DME and clinical research targets that are not good candidatesfor TaqManreg Assay design and suggestions for alternative technologies to use (see theNo TaqMan Assays tab)

Targets of interest that are not covered by the current TaqManreg SNP GenotypingAssay collection can be submitted for Custom TaqManreg SNP Genotyping Assaysdesign

The Custom TaqManreg Assays Design Tool (CADT) is available at wwwthermofishercomtaqmansnpdesign

Order Custom TaqManreg SNP Genotyping Assays by first entering a sequence with theSNP in brackets for example [AG] then submitting the chosen target sites for assaydesign See wwwthermofishercomtaqmansnpdesign

CADT is used to design assays targeting biallelic SNPs or insertiondeletionpolymorphisms and multi‑nucleotide polymorphisms (MNPs) that are 6 bases orfewer in length

Sequences must be SNP and repeat‑masked before submission to CADT Additionallythe genome‑uniqueness for assays must first be established because custom assaysare not compared to the genome (for example by BLAT or BLASTn) to determinetarget specificity Do not submit targets from the ldquoNo TaqMan Assaysrdquo tab (see ldquoPGxtargets not amenable to TaqManreg designldquo on page 20) as assays can be designed thatdo not function properly

For targets that present assay design challenges contact our fee‑for‑design customassay design service at customsolutionslifetechcom

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

OpenArraytrade plate assembly and handling errors

Observation Possible cause Recommended action

Case leaks and bubbles inside the case

Improper sealing of theOpenArraytrade plate in theOpenArraytrade Case can lead to immersion fluidleaks or bubble formation inside the case leadingto uneven heating and imaging throughout PCRand to poor quality genotyping data

The images above are examples of OpenArraytrade

plates that have been affected by immersion fluidleaks The images show where leaked fluid hascondensed on the underside of the heated coverwindows and obscured the view of the through‐holes

The best image in which to detect leaks is thes03_c001_t03_p0001_m2_x3_e1_cp_spotfindtiffimage This image is taken at the start of cyclingwhich is where most leaks occur See ldquoTroubleshoot with cycling and imaging runimagesldquo on page 76

Oily lid or case fromimmersion fluid overflow

Wipe off excess overflow ofimmersion fluid from the lidcase bottom and creviceswith 70 isopropyl alcoholusing a lint-free cloth (thecloth included with theOpenArraytrade plate isacceptable)

Immersion fluid exposed toair for too long

Do not remove the immersionfluid syringe cap or draw airbubbles into the syringe untilyou are ready to load Do notdraw air bubbles into thesyringe

Too large of a bubble insidethe OpenArraytrade case aftersealing

Minimize the size of thebubble by tilting theOpenArraytrade case so that thefill port is at the highest pointSlowly fill the case withimmersion fluid until only asmall air bubble remainsAttach the screw and wipe offany excess oil that may havespilled onto the case

Observation Possible cause Recommended action

Sample blow out during the addition of immersionfluid

The reactions in A12 werecompromised during theaddition of immersion fluidInjecting the immersion fluidtoo quickly can actually purgethe sample out of thethrough-holes near the fillport Often this is caused bythe user not purging thesyringe slightly before use

Dispense a small amount ofimmersion fluid onto a papertowel before use to ensuresmooth operation of thesyringe

Evaporation of reaction mixture in through-holes Too much time elapsed beforeplate was sealed with lid andimmersion fluid In thisexample the top half of eachsubarray was intentionally leftopen to the environment todemonstrate the effect ofevaporation ldquoDonutsrdquo are aresult of the evaporated fluidin the though-holes

Add immersion fluid as soonas the case is removed fromthe plate press to minimizethe likelihood of evaporationthen seal the case with thelid

Appendix A TroubleshootingTroubleshooting unexpected genotyping resultsA

82 Pharmacogenomics Experiments Application Guide

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Genotyper Software) to make distinct genotype calls for assays with merging clusters(see example below) In these cases use the real‑time traces from the QuantStudiotrade

12K Flex Software to review the data by assay and manually call data as necessaryManually adjust the end‑point cycle number to an earlier cycle using the RevealTraces scroll bar the clusters will have a greater degree of separation Use thisadjustment if any real‑time traces do not show a smooth progression in signalthroughout the run

To manually adjust the the end‑point cycle number

1 Open the experiment

2 Select Analysis4Allelic Discrimination Plot from the Experiment Menu paneon the left

3 Select the Options icon (circled in red)

4 Select Reveal traces

5 Use the slider to adjust the end‑point cycle number and optimize allelediscrimination between genotype clusters

6 Click Analyze to update genotype calls

(Optional) Rerunsamples that failto cluster

7 Save the run Take note of the cycle number for each assay that has beenadjusted These numbers can later be entered into the TaqManreg GenotyperSoftware

Note A lower call cycle presently does not transfer to the TaqManreg GenotyperSoftware The software will re‑set the cycle number to 50 cycles Set up a separatestudy with the lower cycle number

Note Ignore the CTFAIL flag for genotyping data Some samples do not haveboth alleles present This flag displays the amplification curve from the absentallele does not meet quality metrics but the amplification will be poor if an alleleis absent

Expected versus unexpected noamp and undetermined calls

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Some TaqManreg Drug Metabolism Genotyping Assays target polymorphisms in genesthat exhibit copy number variation Copy number variation analysis must be done inaddition to genotyping with DME assays

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run near or with the NTCs

bull If a sample contains more than 2 copies of a gene and both SNP alleles arepresent it will fall within the heterozygous cluster or occasionally to one side orthe other of it in which case it may be called as undetermined These should bemanually called as heterozygous for data analysis purposes

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

allele for a given SNP (which can vary between populations particularly for highlypolymorphic SNPs)

The defining variant for a given DME gene star allele may be the only variant neededto identify that particular star allele The defining allele is sometimes referred to as thePrimetag SNPPrime Common allele names are provided for many DME variants in the PGxCommon Markers file See ldquoThe PGx Common Markers fileldquo on page 26

The DME Assay collection variants have been mapped for the genes having publicallele nomenclature sites This allele nomenclature is searchable on the DME assayproduct pages and in the downloadable TaqManreg Drug Metabolism GenotypingAssays Index file available at wwwthermofishercompgx The public allelenomenclature websites provide information on DME gene star allele haplotypes thedefining polymorphisms for these alleles and links to the NCBI dbSNP website forvariants having an reference SNP (refSNP) identifier or rs ID

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Some TaqManreg Drug Metabolism Genotyping Assays target polymorphisms in genesthat exhibit copy number variation Copy number variation analysis must be done inaddition to genotyping with DME assays

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run near or with the NTCs

bull If a sample contains more than 2 copies of a gene and both SNP alleles arepresent it will fall within the heterozygous cluster or occasionally to one side orthe other of it in which case it may be called as undetermined These should bemanually called as heterozygous for data analysis purposes

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

allele for a given SNP (which can vary between populations particularly for highlypolymorphic SNPs)

The defining variant for a given DME gene star allele may be the only variant neededto identify that particular star allele The defining allele is sometimes referred to as thePrimetag SNPPrime Common allele names are provided for many DME variants in the PGxCommon Markers file See ldquoThe PGx Common Markers fileldquo on page 26

The DME Assay collection variants have been mapped for the genes having publicallele nomenclature sites This allele nomenclature is searchable on the DME assayproduct pages and in the downloadable TaqManreg Drug Metabolism GenotypingAssays Index file available at wwwthermofishercompgx The public allelenomenclature websites provide information on DME gene star allele haplotypes thedefining polymorphisms for these alleles and links to the NCBI dbSNP website forvariants having an reference SNP (refSNP) identifier or rs ID

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

All TaqManreg SNP Genotyping Assays Drug Metabolism Genotyping Assays andCustom SNP Genotyping Assays contain sequence‐specific forward and reverseprimers to amplify the polymorphic sequence of interest and two TaqManreg MGBprobes with non‐fluorescent quencher (NFQ)

bull One probe labeled with VICtrade dye detects the Allele 1 sequencebull One probe labeled with FAMtrade dye detects the Allele 2 sequence

TaqManreg DME and SNP Genotyping Assay data is analyzed by cluster plot analysisFAMtrade dye signal is plotted on the Y‑axis and VICtrade dye signal is plotted on the X‑axisSamples homozygous for the FAMtrade‑ or VICtrade‑labeled alleles form clusters along theY‑ or X‑axis respectively whereas heterozygous samples contain both FAMtrade andVICtrade dye signal and will cluster roughly along the diagonal position between thehomozygous clusters

The VICtrade dye probe is associated with the C allele and the FAMtrade dye probe isassociated with the T allele

In this example the SNP alleles (CT) are the reverse complement of those given in thestar allele nomenclature CYP2D64 g1846GgtA This is because the context sequencealleles are provided in the (+) reference genome strand orientation whereas the starallele nucleotide changes are provided with respect to the CYP2D6 gene referencesequence that maps to the (ndash ) genome strand

Several important DME gene variants are triallelic SNPs wherein 3 bases occur at thesame genomic location Triallelic SNP targets can be interrogated using a pair ofTaqManreg assays Each assay contains one probe for the major SNP allele which islabeled with the same reporter dye (VICtrade dye) in both assays and one probe for oneof the minor alleles which is labeled with the second reporter dye (FAMtrade dye) Togenerate accurate sample genotypes the two assays must be run independently onthe same panel of samples and the resulting allelic discrimination plots must beanalyzed in concert comparing the genotype cluster positions from both assays to amap of the true sample genotypes See Table 15 on page ldquoAnalysis guidelines SNPgenotyping assays for triallelic SNPsldquo on page 61 for analysis

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

Assay sets to two highly studied SNPs that have an adjacent less frequently detectedSNPs are available In each case the minor alleles of each SNP are not found togetherin the same haplotype

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

The Centers for Disease Control and Prevention (CDC) provides genetic informationon cell line DNAs that can be used as reference materials for genetic testing and assayvalidation Some of these cell lines were characterized by the Genetic TestingReference Materials Coordination Program (GeT‑RM) One major focus category is theprimeGenetic Inherited Disease amp Pharmacogeneticsprime section Download tables of referencesamples that contain PGxDME or disease allele variants many of which have beenconfirmed by multiple labs and genetic testing technologies can be downloadedfromwwwncdcgovcliaResourcesGETRMMaterialsAvailabilityaspx

Several DME genes occur in CNV regions (see ldquoDME genes and copy numbervariationldquo on page 15) In addition the CYP2D6 and CYP2A6 genes are known torecombine with related pseudogene sequences to generate hybrid genes many ofwhich have decreased or null gene activity TaqManreg Copy Number Assays can beused to detect deletions duplications and hybrid gene alleles TaqManreg CopyNumber Assays for the major known DME genes that exhibit CNV have been pre‑tested on a panel of 45 each African American and Caucasian (the same samples aswere used for TaqManreg Drug Metabolism Genotyping Assay validation studies) Acomplete list of the samples used and their genotypes is available at wwwthermofishercompgx

Good PCR practice

Prevent contamination and non-specific amplification

PCR assays require special laboratory practices to avoid false positive amplificationsThe high throughput and repetition of these assays can lead to amplification of oneDNA molecule

PCR good laboratory practices

When preparing samples for PCR amplificationbull Use a positive‑displacement pipette or aerosol‑resistant pipette tipsbull Follow proper pipette‐dispensing techniques to prevent aerosolsbull Wear clean gloves and a clean lab coat (not previously worn while handlingamplified PCR products or used during sample preparation)

bull Change gloves whenever you suspect that they are contaminatedbull Maintain separate areas and dedicated equipment and supplies for

ndash Sample preparationndash PCR setupndash PCR amplificationndash Analysis of PCR products

bull Do not bring amplified PCR products into the PCR setup areabull Open and close all sample tubes carefully Centrifuge tubes before opening

Avoid splashing or spraying PCR samplesbull Keep reactions and components capped as much as possiblebull Clean lab benches and equipment periodically with 10 bleach solution Use

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

At least two assays are required to detect copy number variation in CYP2A6bull The CYP2A6 intron 7 assay can be used to detect 4 deletion and 1 duplication

alleles This assay will amplify both full length CYP2A6 and the partially activeCYP2A6CYP2A7 hybrid allele CYP2A612 but will not be able to discern them

bull The intron 1 assay can also be used to detect 4 deletion and 1 duplicationalleles This assay will amplify full length CYP2A6 but will not be able to amplifythe CYP2A612 hybrid allele

bull If both CYP2A6 assays are run samples containing 12 alleles can bedistinguished from those containing full‑length alleles For example a 112sample will give 2 copies using the intron 7 assay and 1 copy using the intron 1assay whereas a 11 sample will give 2 copies with both assays

Additionally CYP2A7 assays can be used to corroborate the presence of CYP2A612alleles The CYP2A7 exon 1 assay will amplify the hybrid CYP2A612 allele whereasthe intron 7 assay will not amplify intact CYP2A6 or the CYP2A612 allele

The GSTM1 and GSTT1 genes have a very high frequency of deletion and are entirelymissing in a substantial number of individuals in multiple populations DMEgenotyping assays to variants within these genes will not amplify samples that arehomozygous for the gene deletion samples that are heterogyous for the deletion willrun as a homozygous sample

Special assays

Gender‐specific assays in PGx studies can aid sample tracking The TaqManreg SNPGenotyping Assay C_990000001_10 targets a gender‐specific polymorphic region inthe amelogenin gene that is commonly used in forensic sex determination tests TheVICtrade dye probe detects a 6 base deletion which occurs in the X‐specific amelogeningene whereas the FAMtrade dye probe detects Y‑chromosome sequences In genotypingexperiments male samples run in the heterozygous cluster position and femalesamples run in the VICtrade homozygote cluster Some males lack the Y‐specificamelogenin gene and will type as female Run the C_990000001_10 assay incombination with a Y‑chromosome assay to identify any mistyped samples For moreinformation go to wwwcstlnistgovstrbaseAmelogeninhtm

Order Custom TaqManreg SNP Genotyping Assays by first entering a sequence with theSNP in brackets for example [AG] then submitting the chosen target sites for assaydesign See wwwthermofishercomtaqmansnpdesign

CADT is used to design assays targeting biallelic SNPs or insertiondeletionpolymorphisms and multi‑nucleotide polymorphisms (MNPs) that are 6 bases orfewer in length

Sequences must be SNP and repeat‑masked before submission to CADT Additionallythe genome‑uniqueness for assays must first be established because custom assaysare not compared to the genome (for example by BLAT or BLASTn) to determinetarget specificity Do not submit targets from the ldquoNo TaqMan Assaysrdquo tab (see ldquoPGxtargets not amenable to TaqManreg designldquo on page 20) as assays can be designed thatdo not function properly

Isolate DNA from buccal swabs

This section contains brief procedures For detailed information refer to MagMAXtrade

DNA Multi-Sample Ultra Kit (human buccal swabs) User Guide (Pub No MAN0010293)

Refer to Best Practices for Collection of Buccal Swabs Quick Reference (GenotypingExperiments) (Pub No MAN0014348) for sample collection instructions

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Prepare the Wash Solutions from the concentratesbull Add 25 mL of isopropanol to Wash Solution 1 Concentrate mix and store at

room temperaturebull Add 132 mL of ethanol to Wash Solution 2 Concentrate mix and store at room

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

82 Pharmacogenomics Experiments Application Guide

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Genotyper Software) to make distinct genotype calls for assays with merging clusters(see example below) In these cases use the real‑time traces from the QuantStudiotrade

12K Flex Software to review the data by assay and manually call data as necessaryManually adjust the end‑point cycle number to an earlier cycle using the RevealTraces scroll bar the clusters will have a greater degree of separation Use thisadjustment if any real‑time traces do not show a smooth progression in signalthroughout the run

To manually adjust the the end‑point cycle number

1 Open the experiment

Expected versus unexpected noamp and undetermined calls

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Some TaqManreg Drug Metabolism Genotyping Assays target polymorphisms in genesthat exhibit copy number variation Copy number variation analysis must be done inaddition to genotyping with DME assays

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run near or with the NTCs

bull If a sample contains more than 2 copies of a gene and both SNP alleles arepresent it will fall within the heterozygous cluster or occasionally to one side orthe other of it in which case it may be called as undetermined These should bemanually called as heterozygous for data analysis purposes

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Pairs of assays are available for some adjacent SNP targets for which only threehaplotypes are noted For a given assay to one SNP allele

bull Samples that are heterozygous for the detected haplotypes will run asheterozygous with the assay designed to that haplotype

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported haplotype or the sample can be a heterozygote for a reportedhaplotype and an unreported haplotype of a given assay Samples having just onereported haplotype may run together with or close to those carrying tworeported homozygous haplotypes If a sample close to a homozygous cluster iscalled as undetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported haplotype may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call toPrimenoampPrime

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

Assay sets to two highly studied SNPs that have an adjacent less frequently detectedSNPs are available In each case the minor alleles of each SNP are not found togetherin the same haplotype

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

The primary copy number assay for CNV analysis is the exon 9 Hs00010001_cn assaywhich predominantly detects full‑length CYP2D6 alleles and not hybrid allelescontaining the exon 9 conversion to CYP2D7 sequences Usually it is not necessary todetect these nonfunctional hybrid alleles as they not contribute to CYP2D6metabolizer status (see category A samples in Table 7)

The intron 2 andor intron 6 assays should be run in addition to the exon 9 assaywhen information for both CYP2D6 and hybrid alleles is needed (see Table 7) forexample to characterize samples that are

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

At least two assays are required to detect copy number variation in CYP2A6bull The CYP2A6 intron 7 assay can be used to detect 4 deletion and 1 duplication

bull The intron 1 assay can also be used to detect 4 deletion and 1 duplicationalleles This assay will amplify full length CYP2A6 but will not be able to amplifythe CYP2A612 hybrid allele

bull If both CYP2A6 assays are run samples containing 12 alleles can bedistinguished from those containing full‑length alleles For example a 112sample will give 2 copies using the intron 7 assay and 1 copy using the intron 1assay whereas a 11 sample will give 2 copies with both assays

Additionally CYP2A7 assays can be used to corroborate the presence of CYP2A612alleles The CYP2A7 exon 1 assay will amplify the hybrid CYP2A612 allele whereasthe intron 7 assay will not amplify intact CYP2A6 or the CYP2A612 allele

This section contains brief procedures For detailed information refer to MagMAXtrade

DNA Multi-Sample Ultra Kit (human buccal swabs) User Guide (Pub No MAN0010293)

Refer to Best Practices for Collection of Buccal Swabs Quick Reference (GenotypingExperiments) (Pub No MAN0014348) for sample collection instructions

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Prepare the Wash Solutions from the concentratesbull Add 25 mL of isopropanol to Wash Solution 1 Concentrate mix and store at

room temperaturebull Add 132 mL of ethanol to Wash Solution 2 Concentrate mix and store at room

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

The PharmGKB website (wwwpharmgkborg) provides comprehensive haplotypetranslation tables for CYP gene variants found in the Human Cytochrome P450 (CYP)Allele Nomenclature Database (wwwcypalleleskise) as well as for other drugmetabolism gene variants These tables can be used as reference tables for creatingAlleleTypertrade Software translation tables

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

Several DME genes occur in CNV regions (see ldquoDME genes and copy numbervariationldquo on page 15) In addition the CYP2D6 and CYP2A6 genes are known torecombine with related pseudogene sequences to generate hybrid genes many ofwhich have decreased or null gene activity TaqManreg Copy Number Assays can beused to detect deletions duplications and hybrid gene alleles TaqManreg CopyNumber Assays for the major known DME genes that exhibit CNV have been pre‑tested on a panel of 45 each African American and Caucasian (the same samples aswere used for TaqManreg Drug Metabolism Genotyping Assay validation studies) Acomplete list of the samples used and their genotypes is available at wwwthermofishercompgx

The gDNA samples can be ordered from the Coriell Cell Repositories website (httpccrcoriellorg)

Plasmid controls

We have successfully used synthetic major and minor allele template DNAs clonedinto plasmids to test the performance of over 300 TaqManreg DME Assays In additionto major or minor allele sequences plasmids carry the RNase P RPPH1 gene foraccurate quantitation of plasmids by the standard curve analysis before use ingenotyping experiments Equal quantities of major and minor allele plasmids aremixed together to create heterozygous controls Use the homozygous andheterozygous plasmid controls to demonstrate amplification and detection of all threegenotypes by a given assay Plasmid control samples will often but not alwayscluster with gDNA samples Review example data in the TaqManreg Drug MetabolismGenotyping Assays on OpenArraytrade Plates ppt file from wwwthermofishercompgx

Good PCR practice

Prevent contamination and non-specific amplification

PCR assays require special laboratory practices to avoid false positive amplificationsThe high throughput and repetition of these assays can lead to amplification of oneDNA molecule

PCR good laboratory practices

When preparing samples for PCR amplificationbull Use a positive‑displacement pipette or aerosol‑resistant pipette tipsbull Follow proper pipette‐dispensing techniques to prevent aerosolsbull Wear clean gloves and a clean lab coat (not previously worn while handlingamplified PCR products or used during sample preparation)

bull Change gloves whenever you suspect that they are contaminatedbull Maintain separate areas and dedicated equipment and supplies for

ndash Sample preparationndash PCR setupndash PCR amplificationndash Analysis of PCR products

bull Do not bring amplified PCR products into the PCR setup areabull Open and close all sample tubes carefully Centrifuge tubes before opening

Avoid splashing or spraying PCR samplesbull Keep reactions and components capped as much as possiblebull Clean lab benches and equipment periodically with 10 bleach solution Use

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Genotyper Software) to make distinct genotype calls for assays with merging clusters(see example below) In these cases use the real‑time traces from the QuantStudiotrade

12K Flex Software to review the data by assay and manually call data as necessaryManually adjust the end‑point cycle number to an earlier cycle using the RevealTraces scroll bar the clusters will have a greater degree of separation Use thisadjustment if any real‑time traces do not show a smooth progression in signalthroughout the run

To manually adjust the the end‑point cycle number

1 Open the experiment

2 Select Analysis4Allelic Discrimination Plot from the Experiment Menu paneon the left

3 Select the Options icon (circled in red)

4 Select Reveal traces

5 Use the slider to adjust the end‑point cycle number and optimize allelediscrimination between genotype clusters

6 Click Analyze to update genotype calls

(Optional) Rerunsamples that failto cluster

7 Save the run Take note of the cycle number for each assay that has beenadjusted These numbers can later be entered into the TaqManreg GenotyperSoftware

Note A lower call cycle presently does not transfer to the TaqManreg GenotyperSoftware The software will re‑set the cycle number to 50 cycles Set up a separatestudy with the lower cycle number

8 (Optional) Select Analysis4QC Summary from the Experiment Menu pane toview the QC flags for the runClick each flag to display its meaning and a troubleshooting link appears in theright‑side pane

Note Ignore the CTFAIL flag for genotyping data Some samples do not haveboth alleles present This flag displays the amplification curve from the absentallele does not meet quality metrics but the amplification will be poor if an alleleis absent

Expected versus unexpected noamp and undetermined calls

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Some TaqManreg Drug Metabolism Genotyping Assays target polymorphisms in genesthat exhibit copy number variation Copy number variation analysis must be done inaddition to genotyping with DME assays

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run near or with the NTCs

bull If a sample contains more than 2 copies of a gene and both SNP alleles arepresent it will fall within the heterozygous cluster or occasionally to one side orthe other of it in which case it may be called as undetermined These should bemanually called as heterozygous for data analysis purposes

Triallelic SNP and adjacent SNP targets can be interrogated using a pair of CustomTaqManreg SNP Genotyping Assays Each assay contains one probe for the major SNPallele or haplotype and one probe for one of the minor alleles or haplotypes Afterrunning paired assays in separate reactions on the same genomic DNA samplescompare the results of the two assays to determine the sample genotype For a givenassay it is expected that

bull Samples containing one reported allele may run close to or within a homozygouscluster Any samples running close to homozygous clusters that are called asundetermined should be manually called as homozygous for data analysispurposes

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

Note 1 refers to the reference gene sequence which produces an enzyme withnormal function The reference gene sequence is not necessarily equivalent to thereference genome assembly sequence and it does not necessarily contain the major

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

Assay sets to two highly studied SNPs that have an adjacent less frequently detectedSNPs are available In each case the minor alleles of each SNP are not found togetherin the same haplotype

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

The primary copy number assay for CNV analysis is the exon 9 Hs00010001_cn assaywhich predominantly detects full‑length CYP2D6 alleles and not hybrid allelescontaining the exon 9 conversion to CYP2D7 sequences Usually it is not necessary todetect these nonfunctional hybrid alleles as they not contribute to CYP2D6metabolizer status (see category A samples in Table 7)

The intron 2 andor intron 6 assays should be run in addition to the exon 9 assaywhen information for both CYP2D6 and hybrid alleles is needed (see Table 7) forexample to characterize samples that are

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

bull The intron 1 assay can also be used to detect 4 deletion and 1 duplicationalleles This assay will amplify full length CYP2A6 but will not be able to amplifythe CYP2A612 hybrid allele

bull If both CYP2A6 assays are run samples containing 12 alleles can bedistinguished from those containing full‑length alleles For example a 112sample will give 2 copies using the intron 7 assay and 1 copy using the intron 1assay whereas a 11 sample will give 2 copies with both assays

Additionally CYP2A7 assays can be used to corroborate the presence of CYP2A612alleles The CYP2A7 exon 1 assay will amplify the hybrid CYP2A612 allele whereasthe intron 7 assay will not amplify intact CYP2A6 or the CYP2A612 allele

This section contains brief procedures For detailed information refer to MagMAXtrade

DNA Multi-Sample Ultra Kit (human buccal swabs) User Guide (Pub No MAN0010293)

Refer to Best Practices for Collection of Buccal Swabs Quick Reference (GenotypingExperiments) (Pub No MAN0014348) for sample collection instructions

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

The PharmGKB website (wwwpharmgkborg) provides comprehensive haplotypetranslation tables for CYP gene variants found in the Human Cytochrome P450 (CYP)Allele Nomenclature Database (wwwcypalleleskise) as well as for other drugmetabolism gene variants These tables can be used as reference tables for creatingAlleleTypertrade Software translation tables

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

The Centers for Disease Control and Prevention (CDC) provides genetic informationon cell line DNAs that can be used as reference materials for genetic testing and assayvalidation Some of these cell lines were characterized by the Genetic TestingReference Materials Coordination Program (GeT‑RM) One major focus category is theprimeGenetic Inherited Disease amp Pharmacogeneticsprime section Download tables of referencesamples that contain PGxDME or disease allele variants many of which have beenconfirmed by multiple labs and genetic testing technologies can be downloadedfromwwwncdcgovcliaResourcesGETRMMaterialsAvailabilityaspx

Several DME genes occur in CNV regions (see ldquoDME genes and copy numbervariationldquo on page 15) In addition the CYP2D6 and CYP2A6 genes are known torecombine with related pseudogene sequences to generate hybrid genes many ofwhich have decreased or null gene activity TaqManreg Copy Number Assays can beused to detect deletions duplications and hybrid gene alleles TaqManreg CopyNumber Assays for the major known DME genes that exhibit CNV have been pre‑tested on a panel of 45 each African American and Caucasian (the same samples aswere used for TaqManreg Drug Metabolism Genotyping Assay validation studies) Acomplete list of the samples used and their genotypes is available at wwwthermofishercompgx

The gDNA samples can be ordered from the Coriell Cell Repositories website (httpccrcoriellorg)

Plasmid controls

We have successfully used synthetic major and minor allele template DNAs clonedinto plasmids to test the performance of over 300 TaqManreg DME Assays In additionto major or minor allele sequences plasmids carry the RNase P RPPH1 gene foraccurate quantitation of plasmids by the standard curve analysis before use ingenotyping experiments Equal quantities of major and minor allele plasmids aremixed together to create heterozygous controls Use the homozygous andheterozygous plasmid controls to demonstrate amplification and detection of all threegenotypes by a given assay Plasmid control samples will often but not alwayscluster with gDNA samples Review example data in the TaqManreg Drug MetabolismGenotyping Assays on OpenArraytrade Plates ppt file from wwwthermofishercompgx

Good PCR practice

Prevent contamination and non-specific amplification

PCR assays require special laboratory practices to avoid false positive amplificationsThe high throughput and repetition of these assays can lead to amplification of oneDNA molecule

PCR good laboratory practices

When preparing samples for PCR amplificationbull Use a positive‑displacement pipette or aerosol‑resistant pipette tipsbull Follow proper pipette‐dispensing techniques to prevent aerosolsbull Wear clean gloves and a clean lab coat (not previously worn while handlingamplified PCR products or used during sample preparation)

bull Change gloves whenever you suspect that they are contaminatedbull Maintain separate areas and dedicated equipment and supplies for

ndash Sample preparationndash PCR setupndash PCR amplificationndash Analysis of PCR products

bull Do not bring amplified PCR products into the PCR setup areabull Open and close all sample tubes carefully Centrifuge tubes before opening

Avoid splashing or spraying PCR samplesbull Keep reactions and components capped as much as possiblebull Clean lab benches and equipment periodically with 10 bleach solution Use

DME allele nomenclature

SNPs within drug metabolism genes are often identified by their standardized allelename or star () allele nomenclature (Sim 2010) Star alleles are gene‑level haplotypes(a set of DNA polymorphisms that are often inherited together on the samechromosome) Often these haplotypes have been associated with DME activity levels(for example functional decreased function or nonfunctional variants) Thecombination of star allele haplotypes (that is the diplotype) within a sample can beused to predict its drug metabolizer phenotype (for example ultrarapid extensiveintermediate or poor) Genetic variants within a haplotype can include SNPs InDelsand CNVs The allele nomenclature for a specific gene family is maintained andstandardized by an affiliated group of scientists that curate each site independentlyThis nomenclature is complicated because many alleles contain more than onepolymorphism (that is they are haplotypes) and conversely many polymorphismscan be associated with several alleles

The star allele nomenclature contains the DME gene name such as CYP2D6 followedby a numeric allele name such as 3 A star allele conventionally contains at least onecausative variant (for example a frameshift mutation) Variants are given referencegene andor cDNA coordinates such as g2549delA (full variant name CYP2D63 g2549delA) The causative star allele variant can be associated with other nucleotidevariants in different haplotypes groups such sub‑alleles are denoted by lettersfollowing the numeric allele identifier (for example 3A) On the Cytochrome P450(CYP) Allele Nomenclature web site the defining causative variant for a star allele isoften in bold font

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 gene is the most highly polymorphic and complex of the DME genesOver 100 star allele groups have been identified by the Cytochrome P450Nomenclature Committee (wwwcypalleleskise) At least 4 of these groups give riseto alleles with substrate‑dependent reduced enzyme activity and more than 20 do notencode functional enzymes

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Genotyper Software) to make distinct genotype calls for assays with merging clusters(see example below) In these cases use the real‑time traces from the QuantStudiotrade

12K Flex Software to review the data by assay and manually call data as necessaryManually adjust the end‑point cycle number to an earlier cycle using the RevealTraces scroll bar the clusters will have a greater degree of separation Use thisadjustment if any real‑time traces do not show a smooth progression in signalthroughout the run

To manually adjust the the end‑point cycle number

1 Open the experiment

2 Select Analysis4Allelic Discrimination Plot from the Experiment Menu paneon the left

3 Select the Options icon (circled in red)

4 Select Reveal traces

5 Use the slider to adjust the end‑point cycle number and optimize allelediscrimination between genotype clusters

6 Click Analyze to update genotype calls

(Optional) Rerunsamples that failto cluster

7 Save the run Take note of the cycle number for each assay that has beenadjusted These numbers can later be entered into the TaqManreg GenotyperSoftware

Note A lower call cycle presently does not transfer to the TaqManreg GenotyperSoftware The software will re‑set the cycle number to 50 cycles Set up a separatestudy with the lower cycle number

8 (Optional) Select Analysis4QC Summary from the Experiment Menu pane toview the QC flags for the runClick each flag to display its meaning and a troubleshooting link appears in theright‑side pane

Note Ignore the CTFAIL flag for genotyping data Some samples do not haveboth alleles present This flag displays the amplification curve from the absentallele does not meet quality metrics but the amplification will be poor if an alleleis absent

Expected versus unexpected noamp and undetermined calls

For certain assays it is expected that there will be some samples that legitimately failto amplify or have an undetermined genotype call These include samples run withassays that interrogate gene variants that are associated with copy number variationand with assays that detect triallelic SNPs or adjacent SNPs See ldquoAnalysis guidelinesDME genotyping assays for genes in copy number variation regionsldquo on page 61 and ldquoAnalysis guidelines SNP genotyping assays for triallelic SNPsldquo on page 61 for detailson how to analyze the data for such assays

Some TaqManreg Drug Metabolism Genotyping Assays target polymorphisms in genesthat exhibit copy number variation Copy number variation analysis must be done inaddition to genotyping with DME assays

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run near or with the NTCs

bull If a sample contains more than 2 copies of a gene and both SNP alleles arepresent it will fall within the heterozygous cluster or occasionally to one side orthe other of it in which case it may be called as undetermined These should bemanually called as heterozygous for data analysis purposes

Triallelic SNP and adjacent SNP targets can be interrogated using a pair of CustomTaqManreg SNP Genotyping Assays Each assay contains one probe for the major SNPallele or haplotype and one probe for one of the minor alleles or haplotypes Afterrunning paired assays in separate reactions on the same genomic DNA samplescompare the results of the two assays to determine the sample genotype For a givenassay it is expected that

bull Samples containing one reported allele may run close to or within a homozygouscluster Any samples running close to homozygous clusters that are called asundetermined should be manually called as homozygous for data analysispurposes

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

For TaqManreg Drug Metabolism Genotyping Assays having a reported AppliedBiosystemstrade MAF in the African American or Caucasian populations heterozygousor minor allele homozygous samples may be used as reference or control samples ingenetic testing and assay performance studies A complete list of the samples usedand their genotypes is available at thermofishercom

TaqManreg Drug Metabolism Genotyping Assays

The TaqManreg Drug Metabolism Genotyping Assay a collection of approximately2700 assays detect potentially causative SNP MNP or InDel polymorphisms in 221drug metabolism enzyme (DME) and associated transporter genes The DME assayswere designed using an optimized DME assay design algorithm that uses a high levelof bioinformatics to ensure a lack of underlying polymorphisms and high targetspecificity (that is gene family members and pseudogenes will not amplify) Assaysto more difficult targets underwent manual design All DME Assays underwentstringent wet‑lab testing including running with 180 unique DNA samples from fourdifferent populations (African American Caucasian Chinese and Japanese)

The TaqManreg SNP Genotyping Assays were designed using a related highlyvalidated SNP assay design algorithm The SNP assays are functionally tested (that isfor amplification and clustering capabilities) when first manufactured on 20 unrelatedgDNA samples from three populations (African American Caucasian and Japanese)In addition over 300 high value TaqManreg DME and SNP assays were tested with 44African American and Caucasian samples and synthetic templates representing each

For certain DME targets two SNPs are located adjacent to one another Thiscomplicates the SNP genotype analysis because for each assay the probes will fail tobind target sequences when the adjacent SNP is present However when the adjacentSNPs are present in only 3 haplotypes these SNPs can be interrogated similarly totriallelic SNPs using two assays (see ldquoTaqManreg Drug Metabolism Genotyping Assayfor genotyping triallelic SNPsldquo on page 13)

Assay sets to two highly studied SNPs that have an adjacent less frequently detectedSNPs are available In each case the minor alleles of each SNP are not found togetherin the same haplotype

TaqManreg Copy Number Assays

Copy number variation must be assessed for DME genes known to exhibit copynumber variation (see ldquoPre‑tested TaqManreg Copy Number Assays for select DMEgenesldquo on page 16) TaqManreg Copy Number Assays are run simultaneously with aTaqManreg Copy Number Reference Assay in a duplex real‑time polymerase chainreaction (PCR) TaqManreg Copy Number Assays detect the target gene or genomicsequence of interest and the TaqManreg Copy Number Reference Assay detects asequence known to exist in two copies in a diploid genome (for example the humanRNase P H1 RNA gene) Relative quantitation (RQ) using the comparative Ct (ΔΔCt)method is used to determine the number of copies of the target sequence in each testsample

bull TaqManreg Copy Number Assays contain two primers and a FAMtrade dye‑labeledMGB probe to detect the genomic DNA target sequence

bull TaqManreg Copy Number Reference Assays contain two primers and a VICtrade

dye‑labeled TAMRAtrade probe to detect the genomic DNA reference sequence

TaqManreg Copy Number Assays are ordered as single tube assays (see ldquoSingle tubeproducts and formatsldquo on page 27) and run on 96‑well and 384‑well plates onApplied Biosystemstrade Real‑Time instruments including the QuantStudiotrade 12K FlexReal‑Time PCR System There are currently no copy number assays developed for theOpenArraytrade plate

Several DME genes exhibit copy number variation (CNV) or other structuralalterations due to recombination and gene conversions events between highly relatedloci (He 2011)

For DME gene variants that are associated with copy number variation run bothDME genotyping assays and copy number assays to determine sample genotypes

For DME assays that target a deleted or duplicated gene (for example CYP2D6)bull samples that contain 0 copies of the gene will not amplifybull samples with 1 or more gene copies that are homozygous for the SNP allele will

cluster togetherbull samples with more than 2 gene copies that are heterozygous may run within the

2‑copy heterozygous cluster or between it and one of the homozygous clusters

To discern the sample genotype copy number quantitation of the gene target must bedone to determine which samples carry gene deletions or duplications Additionallyuse of multiple copy number assays for a gene may be required for hybrid geneanalysis

Note The copy number assays are not SNP allele‐specific and cannot be used todetermine which SNP allele is duplicated when a sample is heterozygous and hasthree gene copies

A protocol has been developed for determining allele‐specific copy number ofCYP2D6 alleles by digital PCR For more information see CYP2D6 Allele-specific CopyNumber Analysis Quick Reference (Pub No MAN0011114)

The CYP2D6 alleles are composed of SNP and InDel variants CNVs and hybridalleles formed by recombination between CYP2D6 and highly related upstreampseudogene CYP2D7 sequences Individuals may carry null alleles (5) or extracopies of CYP2D6 (1 2 4 910 17 35) Some CYP2D6 alleles contain sequencesderived from the highly homologous CYP2D7 pseudogene for example CYP2D636as well as 4N 57 and 83 contains a gene conversion to CYP2D7 sequences in exon9 associated with negligible CYP2D6 enzyme activity (Gaedigk 2006)

Three different copy number assays to CYP2D6 sequences are available fordetermining CYP2D6 gene copy number and to aid identification of some hybridalleles (see ldquoPre‑tested TaqManreg Copy Number Assays for select DME genesldquo onpage 16)

The primary copy number assay for CNV analysis is the exon 9 Hs00010001_cn assaywhich predominantly detects full‑length CYP2D6 alleles and not hybrid allelescontaining the exon 9 conversion to CYP2D7 sequences Usually it is not necessary todetect these nonfunctional hybrid alleles as they not contribute to CYP2D6metabolizer status (see category A samples in Table 7)

The intron 2 andor intron 6 assays should be run in addition to the exon 9 assaywhen information for both CYP2D6 and hybrid alleles is needed (see Table 7) forexample to characterize samples that are

IMPORTANT Always use the CYP2D6 exon 9 copy number assay to detect true geneduplication events CYP2D6 intron 2 or intron 6 copy number assays should not beused alone to detect CYP2D6 duplications as they will also detect nonfunctionalhybrid alleles that do not represent duplications and that do not contribute toCYP2D6 metabolizer status

CYP2A6 alleles defined by the Cytochrome P450 Nomenclature Committee(wwwcypalleleskise) include at least four non‑functional alleles and severalreduced function alleles The genotyping of CYP2A6 alleles is complicated by thepresence of copy number variant deletion (4) and duplication (1) alleles and hybridalleles formed by recombination with upstream pseudogene CYP2A7 sequences forexample the reduced function 12 allele contains exons 1‑2 of CYP2A7 origin andexons 3‑9 of CYP2A6 origin (Oscarson 2002)

At least two assays are required to detect copy number variation in CYP2A6bull The CYP2A6 intron 7 assay can be used to detect 4 deletion and 1 duplication

bull The intron 1 assay can also be used to detect 4 deletion and 1 duplicationalleles This assay will amplify full length CYP2A6 but will not be able to amplifythe CYP2A612 hybrid allele

bull If both CYP2A6 assays are run samples containing 12 alleles can bedistinguished from those containing full‑length alleles For example a 112sample will give 2 copies using the intron 7 assay and 1 copy using the intron 1assay whereas a 11 sample will give 2 copies with both assays

Additionally CYP2A7 assays can be used to corroborate the presence of CYP2A612alleles The CYP2A7 exon 1 assay will amplify the hybrid CYP2A612 allele whereasthe intron 7 assay will not amplify intact CYP2A6 or the CYP2A612 allele

This section contains brief procedures For detailed information refer to MagMAXtrade

DNA Multi-Sample Ultra Kit (human buccal swabs) User Guide (Pub No MAN0010293)

Refer to Best Practices for Collection of Buccal Swabs Quick Reference (GenotypingExperiments) (Pub No MAN0014348) for sample collection instructions

bull Perform all steps at room temperature (20ndash25degC) unless otherwise notedbull Equilibrate buccal swabs to room temperature to maximize DNA recoverybull Remove the buccal swabs from the lysate

ndash Option 1 (Preferred) Transfer the lysate to a new plateThis option eliminates contamination risks and saves time To transferlysates set a multi‑channel micropipettor to ~300 microL and transfer one row atthe time Each well should contain 200ndash250 microL after transfer

ndash Option 2 Remove the swabs from the plate using forcepsRinse the forceps in 70 ethanol between samples to prevent cross‑contamination Press the swabs against the side of the well when removingthem to prevent sample loss

bull Cover the plate during the incubation and shaking steps to prevent spill‑over andcross‑contamination The same MicroAmptrade Clear Adhesive Film can be usedthroughout the procedure unless it becomes contaminated

bull If you use a plate shaker other than the recommended shaker verify thatndash The plate fits securely on your plate shakerndash The recommended speeds are compatible with your plate shaker Ideal

shaker speeds allow for thorough mixing without splashingbull Per‑plate volumes for reagent mixes are sufficient for one plate plus overage To

calculate volumes for other sample numbers refer to the per‑well volume andadd 5 overage

bull (Optional) To prevent evaporation and contamination cover the preparedprocessing plates with paraffin film until they are loaded into the instrument

(Optional) Guidelines for improving yields

bull This procedure is optimized for processing of one swab per well It is possible toprocess two swabs in one well when a higher concentration of DNA is required

bull If the DNA yield is lower than expected extend the Proteinase K digestion to45 minutes

bull To further improve recovery digest with Proteinase K overnight at 50degC

Prepare the Wash Solutions from the concentratesbull Add 25 mL of isopropanol to Wash Solution 1 Concentrate mix and store at

room temperaturebull Add 132 mL of ethanol to Wash Solution 2 Concentrate mix and store at room

Recommended Run OpenArraytrade SNP genotyping experiments inreal-time mode

We recommend running all OpenArraytrade plates on a QuantStudiotrade instrument in real‑time experiment mode This recommendation allows observation of genotyping dataover time to evaluate the accuracy of genotype calls by observing the location of agiven sample relative to others throughout all cycles

The following example shows how calls based on end‑point reads could be incorrectwhen the DNA concentration is higher than the recommended amount

Note Generally a CT value of ~25 indicates that the sample input is approximately250 haploid copies which is the recommended input amount per 33‑nL reaction forOpenArraytrade genotyping plates This corresponds to 825 pg of DNA per PCR reactionusing a stock solution of 50 ngmicroL

Analysis guidelines DME genotyping assays for genes in copynumber variation regions

Some TaqManreg DME Assays target polymorphisms in genes that exhibit copy numbervariation including CYP2D6 CYP2A6 CYP2E1 GSTM1 GSTT1 and SULT1A1 Copynumber variation analysis must be done in addition to genotyping with DME assaysThe frequency of the CYP2D6 CYP2A6 CYP2E1 and SULT1A1 gene deletions arelow and samples that carry no copies of these genes will be rare However thefrequency of deletion of GSTM1 and GSTT1 genes is very high in a number ofpopulations and complete absence of these genes in individuals is common

For a given DME assay that targets a gene that can be deleted or duplicated thefollowing genotyping results are possible

bull If both copies of a gene are deleted in a sample (copy number of 0) samples willnot be amplified and will run with NTCs If a sample running near the NTCs hasbeen called as undetermined that call can be manually adjusted to PrimenoampPrime

bull If a sample contains 1 2 or more than 2 copies of the gene and only one SNPallele is present the samples will cluster together in a homozygous alleleClusters will sometimes show some splitting samples containing less target canrun closer to the NTCs than those containing more copies of the target

bull If a sample carries more than 2 copies of a gene and both SNP alleles are presentit will fall within the heterozygous cluster or off to one side or the other of thecluster (that is the heterozygous cluster may exhibit some spreading) If a sampleclose to the heterozygous cluster has been called as undetermined manuallyadjust the call to heterozygous

Analysis guidelines SNP genotyping assays for triallelic SNPs

Triallelic SNPs are interrogated using two TaqManreg assaysExample

bull Assay 1 Major SNP allele (labeled with VICtrade dye) and first minor allele (labeledwith FAMtrade dye)

bull Assay 2 Major SNP allele (labeled with VICtrade dye) and second minor allele(labeled with FAMtrade dye)

Expected results

bull Samples that are heterozygous for the detected SNP alleles will run asheterozygous with the assay designed to that mutant allele

bull Samples running in or near a homozygous cluster can be a true homozygote forthe reported allele or the sample can be a heterozygote for a reported allele andfor the unreported SNP allele of a given assay Samples with one reported allelein an assay can sometimes run together or close to those carrying two reportedhomozygous alleles If a sample close to a homozygous cluster is called asundetermined manually change the call to homozygous

bull Samples that are homozygous for the unreported SNP allele may cluster withNTCs or may exhibit weak amplification due to probe nonspecific activity If aweakly amplifying sample is called as undetermined manually adjust the call tonoamp

Introduction to copy number analysis

Copy number variation must be assessed for DME genes that are known to exhibitcopy number variation For full details on running TaqManreg Copy Number Assayexperiments refer to the TaqManreg Copy Number Assays Protocol (Pub No 4397425)The protocol provides step‑by‑step instructions for performing and analyzing copynumber variation quantitation experiments using TaqManreg Copy Number Assays andTaqManreg Copy Number Reference Assays for the ViiAtrade 7 Real‑Time PCR System Thesame instructions apply for running experiments on the QuantStudiotrade 12K Flex Real‑Time PCR System

How TaqManreg Copy Number Assays work

TaqManreg Copy Number Assays are run simultaneously with a TaqManreg CopyNumber Reference Assay in a duplex real‑time PCR reaction The TaqManreg CopyNumber Assay detects the target gene or genomic sequence of interest and theTaqManreg Copy Number Reference Assay detects a sequence that is known to exist intwo copies in a diploid genome (for example the human RNase P H1 RNA gene)

The number of copies of the target sequence in each test sample is determined byrelative quantification (RQ) using the comparative CT (ΔΔCt) method This methodmeasures the Ct difference (ΔCt) between target and reference sequences thencompares the ΔCt values of test samples to a calibrator sample(s) known to have twocopies of the target sequence The copy number of the target is calculated to be twotimes the relative quantity because the human genome is diploid

In a copy number quantification reaction purified genomic DNA is combined withbull The TaqManreg Copy Number Assay containing two primers and a FAMtrade

dye‑labeled MGB probe to detect the genomic DNA target sequencebull The TaqManreg Copy Number Reference Assay containing two primers and a

VICtrade dye‑labeled TAMRAtrade probe to detect the genomic DNA referencesequence

bull One of the following master mixesndash (Recommended) TaqPathtrade ProAmptrade Master Mixndash TaqManreg Genotyping Master Mix

Reactions are run on an Applied Biosystemstrade Real‑Time PCR System Afteramplification data files containing the sample replicate CT values for each reporterdye can be exported from the real‑time PCR instrument software and imported into asoftware analysis tool Applied Biosystemstrade CopyCallertrade Software is recommendedfor post‑PCR data analysis of copy number quantification experiments

Introduction to AlleleTypertrade Software

AlleleTypertrade Software is an automated data analysis application that translatesgenetic pattern information from TaqManreg SNP Genotyping Assay andor TaqManreg

Copy Number Assay results to user‐defined genotype or diplotype nomenclature Forcomplete instructions on how to use AlleleTypertrade Software and to create user‐definedtranslation tables see the AlleleTypertrade Software User Guide (Pub No 4486002)

AlleleTypertrade Software is a flexible tool used for conversion of sample genotypeinformation for single or multiple genes or loci to the desired nomenclature forexample the PGx gene‑level star () allele nomenclature to describe SNP InDel orcopy number variant genotypes (for example for the Cytochrome P450 genes) Staralleles are haplotypes that can contain multiple variants these are associated withfunctional or nonfunctional gene products AlleleTypertrade Software can translate thegenotype results for special cases including triallelic or adjacent SNP interrogationusing two TaqManreg SNP Assays or the software can simply provide a name for aparticular genetic outcome for a given SNP or copy number assay

Before creating a translation table or translator consider all of the TaqManreg SNPGenotyping Assays (includes TaqManreg DME Genotyping Assays) and TaqManreg CopyNumber Assays that will be used in your project and which of these you want toinclude in a translation table for reporting sample genotype results using specificnomenclature SNP assay and copy number assay experiment data generated on anApplied Biosystemstrade real‑time PCR system must be analyzed by TaqManreg GenotyperSoftware and CopyCallertrade Software respectively because results files exported fromthese software systems are input files for AlleleTypertrade Software

AlleleTypertrade Software aids creation of translation tables by automatically convertingmonoallelic translation tables containing haplotype patterns to biallelic translatorscontaining diplotype or genotype patterns After examining biallelic translators forcompleteness and accuracy they are imported into AlleleTypertrade Software along withTaqManreg Genotyper Software data files andor CopyCallertrade Software data filesAlleleTypertrade Software then matches the sample genetic pattern data to patterns in thebiallelic translator and reports back the designated nomenclature for each matchingpattern on a gene‑by‑gene basis when a multigene translator is used

PGx translation tables

The translation tables provided by both Thermo Fisher Scientific and PharmGKB usethe convention whereby the variant alleles are provided in the (+) strand orientationof the reference genome Likewise TaqManreg SNP and DME Genotyping Assayscontext sequences are provided in the (+) genome strand orientation In contrast the allele nomenclature for many PGx genes does not follow this convention the variantalleles might map to the (ndash) strand of the reference genome and thus are given in thereverse complement orientation (for example CYP2D6 which maps to the (ndash) genomestrand)

For successful translation of sample genotyping results by AlleleTypertrade Software thebase alleles used in the translation table must match the base alleles used in theTaqManreg Genotyper Software results files In addition the assay identifiers mustmatch between the translation table and the TaqManreg Genotyper Software andorCopyCallertrade Software results files

Sources of PGx translation information and example translationtables

Thermo Fisher Scientific provides example AlleleTypertrade Software translation tabletemplate files and translation tables (including monoallelic and biallelic tables singlegene and multigene translators) for commonly tested drug metabolism gene variantsThese files can be downloaded from the AlleleTypertrade Software web page at wwwthermofishercompgx and used as templates for creating translators specific toa TaqManreg Assays panel

The PharmGKB website (wwwpharmgkborg) provides comprehensive haplotypetranslation tables for CYP gene variants found in the Human Cytochrome P450 (CYP)Allele Nomenclature Database (wwwcypalleleskise) as well as for other drugmetabolism gene variants These tables can be used as reference tables for creatingAlleleTypertrade Software translation tables

If a sample fails to cluster well with other samples or fails to amplify properly withone or more assays (that is there are UND and NOAMP calls in the run) rerun suchsamples using single tube DME assays on 96‑well or 384‑well plates We recommendrunning control gDNA samples along with the unknown samples or use a referencepanel (see ldquo(Optional) Generate a reference panelldquo on page 58) The controls will helpto provide more accurate genotype calling of the unknown samples

Troubleshooting genotype calls for assays with merging clusters

It can be difficult for the secondary analysis software (for exampleTaqManreg

Preamplification of low-concentration gDNA

Overview

Preamplification in OpenArraytrade experiments helps to ensure sufficient templatecopies in the 33‑nL qPCR reaction At low template copy numbers stochastic effectscan dominate the reaction because the random events at each template moleculerepresent a large portion of the potential extension events Stochastic events in qPCRreactions are generally dominant at levels of lt10 template copies and negligible atlevels of gt100 template copies

The standard OpenArraytrade protocol for human SNP assays recommends starting with50 ngmicroL of genomic DNA When diluted 50 in master mix and loaded into a33‑nL reaction chamber the final template amount is 825 pg This converts to250 genomic copies (125 genomic copies for each allele in a heterozygote)

Preamplification can also be used to dilute PCR inhibitors from sample preparationsthat are of sufficient DNA concentration but contain impurities and therefore do notamplify well with the TaqManreg OpenArraytrade Genotyping Master Mix

This protocol describes targeted multiplex preamplification of 1 to 256 SNP locilocated in human genomic DNA samples A multiplex pool of TaqManreg SNPGenotyping Assays is used to simultaneously preamplify up to 256 targetpolymorphisms in a single reaction using a reduced amount of input DNA sample

The preamplification product can be used as the sample template input for SNPgenotyping reactions with any of the individual TaqManreg SNP Genotyping Assaysincluded in the multiplex preamplification assay pool Perform genotypingexperiments using the individual TaqManreg SNP Genotyping Assays following thestandard protocol except substituting preamplified product for genomic DNAsample It is not necessary to quantify or normalize preamplified product Thepreamplified sample can be added directly into the reaction plate or further diluted in1X TE Buffer to the desired concentration

For specific applications a custom OpenArraytrade Preamp Pool specific for yourTaqManreg SNP assay panel can be ordered along with your OpenArraytrade plate (contactyour sales representative for details)

Note The protocol is compatible with TaqManreg SNP Genotyping Assays but is notrecommended for use with TaqManreg Copy Number Assays

Guidelines for starting DNA sample concentration

DNA sample concentration Preamplification Recommendation

lt04 ngμL Not recommended Preamplification of DNA at concentrations lt04 ngμL isnot recommended due to the potential for stochasticevents arising from low target number in the early roundsof the preamplification and qPCR reactions

04 ngμL to 40 ngμL Ideal preamplificationrange

The preamplification protocol was developed usinggenomic DNA samples within a starting concentrationrange of 04 ngμL to 40 ngμL and a total of 05 ng to5 ng in the preamplification reaction

Optimal performance will be achieved if the startingconcentration of genomic DNA samples is near themiddle of the working range (25 ngμL) Ourrecommended protocol for accurate quantification ofhuman gDNA samples using the RNase P DetectionReagents Kit can be found in Appendix B of thePharmacogenomics Experiments User Guide

4 ngμL to 25 ngμL User discretion Samples at these concentrations may be preamplifiedwithout dilution but these are out of the optimal range

gt25 ngμL Not recommended Samples with DNA sample concentrations gt25 ngμL donot require preamplification If samples at theseconcentrations do not amplify well with SNP assays theylikely contain PCR inhibitors If this is the case highconcentration DNA samples may yield good results afterdilution and preamplification of these samples may beunnecessary

Note 1 ng of human genomic DNA = 300 genomic copies or 150 copies of each allelein a heterozygote

Controls for genotyping and copynumber experiments

Overview

Laboratories can verify the performance of selected TaqManreg SNP Genotyping Assaysand TaqManreg Drug Metabolism Genotyping Assays on OpenArraytrade plates by usingsamples that represent all three genotypes (homozygous major allele homozygousminor allele and heterozygous) to test for both amplification and cluster separationA laboratory may prefer to use samples that represent at least two genotypes(homozygous major and minor alleles or homozygous major allele and heterozygous)to test that both assay probes function Ideally gDNA samples of known genotypesare used for such experiments However for rare DME variants that are notwell‑represented in populations it may be necessary to use synthetic templates

This Appendix includes information on sources of control cell line sample DNAs forDME and SNP genotyping assays as well as for copy number assays It also includesinformation on ordering synthetic template DNAs in plasmids

Sources of reference materials

This section describes some publicly available sources for reference or controlmaterials that can be used in genetic testing and assay performance experiments

All TaqManreg Drug Metabolism Genotyping Assays were run on 180 unique DNAsamples from four different populations in assay performance and reproducibilitytesting Samples tested included a panel of 45 African American and 45 Caucasiansamples obtained from the Coriell Cell Repositories and a panel of 45 Japanese and 45Chinese samples provided by a collaborator The minor allele frequencies determinedfor each assay are provided at thermofishercom (assay search results) and in theDME Index

Note Many of the polymorphisms interrogated by this assay collection have verylow minor allele frequencies (MAFs) of less than 1 thus the minor allele was notdetected for all assays within the 180 test samples

Several DME genes occur in CNV regions (see ldquoDME genes and copy numbervariationldquo on page 15) In addition the CYP2D6 and CYP2A6 genes are known torecombine with related pseudogene sequences to generate hybrid genes many ofwhich have decreased or null gene activity TaqManreg Copy Number Assays can beused to detect deletions duplications and hybrid gene alleles TaqManreg CopyNumber Assays for the major known DME genes that exhibit CNV have been pre‑tested on a panel of 45 each African American and Caucasian (the same samples aswere used for TaqManreg Drug Metabolism Genotyping Assay validation studies) Acomplete list of the samples used and their genotypes is available at wwwthermofishercompgx

The gDNA samples can be ordered from the Coriell Cell Repositories website (httpccrcoriellorg)

Plasmid controls

We have successfully used synthetic major and minor allele template DNAs clonedinto plasmids to test the performance of over 300 TaqManreg DME Assays In additionto major or minor allele sequences plasmids carry the RNase P RPPH1 gene foraccurate quantitation of plasmids by the standard curve analysis before use ingenotyping experiments Equal quantities of major and minor allele plasmids aremixed together to create heterozygous controls Use the homozygous andheterozygous plasmid controls to demonstrate amplification and detection of all threegenotypes by a given assay Plasmid control samples will often but not alwayscluster with gDNA samples Review example data in the TaqManreg Drug MetabolismGenotyping Assays on OpenArraytrade Plates ppt file from wwwthermofishercompgx

Good PCR practice

Prevent contamination and non-specific amplification

PCR assays require special laboratory practices to avoid false positive amplificationsThe high throughput and repetition of these assays can lead to amplification of oneDNA molecule

PCR good laboratory practices

When preparing samples for PCR amplificationbull Use a positive‑displacement pipette or aerosol‑resistant pipette tipsbull Follow proper pipette‐dispensing techniques to prevent aerosolsbull Wear clean gloves and a clean lab coat (not previously worn while handlingamplified PCR products or used during sample preparation)

bull Change gloves whenever you suspect that they are contaminatedbull Maintain separate areas and dedicated equipment and supplies for

ndash Sample preparationndash PCR setupndash PCR amplificationndash Analysis of PCR products

bull Do not bring amplified PCR products into the PCR setup areabull Open and close all sample tubes carefully Centrifuge tubes before opening

Avoid splashing or spraying PCR samplesbull Keep reactions and components capped as much as possiblebull Clean lab benches and equipment periodically with 10 bleach solution Use
