Harnessing the power of genetics in whole genome analysis of
hereditary cancer susceptibility
Jonathan S. Berg, MD/PhD Department of Genetics

![Page 23: Session 3: Genetics and Genomics - UNC Linebergercancer.unc.edu/lcccnewsletter/genetics-and-genomics.pdf · Chemistry v3 enabled capability (current): up to 500-600Gb per run Capability](https://reader034.fdocuments.us/reader034/viewer/2022051510/5fee73b7f1e8083f0e68ee89/html5/thumbnails/23.jpg)
Clinical Cancer Genetics at UNC
• Assessment and genetic testing for suspected hereditary cancer predisposition
• >5000 families evaluated over 15 years
• Majority of patients with breast/ovarian cancer, many with GI cancer, polyposis
• Comprehensive database of pedigrees, risk calculations, and genetic test results
![Page 24: Session 3: Genetics and Genomics - UNC Linebergercancer.unc.edu/lcccnewsletter/genetics-and-genomics.pdf · Chemistry v3 enabled capability (current): up to 500-600Gb per run Capability](https://reader034.fdocuments.us/reader034/viewer/2022051510/5fee73b7f1e8083f0e68ee89/html5/thumbnails/24.jpg)
Hypothesis • Inidividuals highly suspicious for hereditary
cancer, who test negative for known genes,
carry mutations of novel cancer susceptibility
genes
Plan
• Identify variants using whole genome sequencing in a subset of study participants/families
• Select candidate mutations
• Test other patients for mutations in the same gene
![Page 25: Session 3: Genetics and Genomics - UNC Linebergercancer.unc.edu/lcccnewsletter/genetics-and-genomics.pdf · Chemistry v3 enabled capability (current): up to 500-600Gb per run Capability](https://reader034.fdocuments.us/reader034/viewer/2022051510/5fee73b7f1e8083f0e68ee89/html5/thumbnails/25.jpg)
Analytic approaches
• Family-based – WGS in paired affected
family members
– Identification of rare, likely deleterious variants that are shared
– Segregation analysis in other family members
• Phenotype-based – WGS in multiple unrelated
individuals
– Identification of genes in which affected individuals have rare, likely deleterious variants
– Utilize pedigree information regarding inheritance pattern
![Page 26: Session 3: Genetics and Genomics - UNC Linebergercancer.unc.edu/lcccnewsletter/genetics-and-genomics.pdf · Chemistry v3 enabled capability (current): up to 500-600Gb per run Capability](https://reader034.fdocuments.us/reader034/viewer/2022051510/5fee73b7f1e8083f0e68ee89/html5/thumbnails/26.jpg)
Enrollment
• Study team identified and triaged >100 probands

Cancer is a Genetic Disease:
• “Somatic” mutations occur in cancers and determine the biology of the disease.
• Identifying the pathogenic “driver” mutations that cause the cancer will predict prognosis and response to therapy.
• Identification of all driver mutations is needed, but is not currently done.

Why Use Sequence Capture:
• Separates diagnostic approach from discovery
• Estimated that > 90% of driver mutations in common solid cancers occur in < 50 genes
• Capture target is flexible
• Capture can save time, effort and money

Using NextGen for Better Cancer Care:
• We can sequence 50-150 genes in patients’ tumor / germline in <4 weeks for < $1,500 per patient
• We see the vast majority of genetic events (PMs, dels, amps)
• Expect IRB approval for use in any patient summer of 2011,
• Plan to sequence ~10K patient tumors from the UCRF-funded cancer survivorship cohort
• Validated discoveries will be disclosed to patients and physicians when consistent with treatment guidelines, or if standard of care has been exhausted

Preliminary analysis
• 4 tumors selected for initial analysis, 2 paired normals for comparison.
• ChIP-seq
– H3K4me1 (poised)
– H3K4me3 (active)
– H3K27me1 (repressed)
• FAIRE
– Global regions of open chromatin

UCRF Proposal
• Perform FAIRE and Histone methylation-specific ChIP-seq on increased numbers of selected tumors.
• Selection criteria:
– ccA or ccB subtype
– IHC detection of H3 methylation marks
– PBRM1 mutated vs wild type

Conclusions:
• This analysis will enable us to:
– Determine global chromatin remodeling effect of PBRM1 mutations on RCC.
– Link transcriptional readouts to chromatin patterns
– Identify common elements that underlie the transforming events in RCC
