Characterizing Environmental Exposures that Impact Human Health Outcomes
Rappaport and Smith, Science 330:460-1, 2010
•Environment is defined as the body’s internal chemical environment
• Exposure is defined as the amounts of biologically active chemicals in this internal environment

Nitric Oxide Synthase
• NOS3 variants influence (raise) homocysteine concentrations
• smoking compromises NOS3 activity
• folate intake influences (lowers) homocysteine concentrations
• is clefting risk from NOS3 variants modified by smoking and further modified by vitamin intake (folic acid)?

Neural Tube Defects 250-300,000 NTD births annually
worldwide; 3,000 in US
Result in lifelong disability
Problems with bladder, bowel, and sexual function
Learning and developmental problems
Orthopedic problems
Some NTDs are preventable-Approx. 20% reduction since folate fortification in US

NTDs are Complex Traits
• They have a strong genetic component
• They also require a significant environmental interaction in order to express the abnormal phenotype
![Page 14: Of Mice and Men: Using Animal Models to Study Gene … · Of Mice and Men: Using Animal Models to Study Gene-Environment Interactions Richard H. Finnell Dell Pediatric Research Institute](https://reader033.fdocuments.us/reader033/viewer/2022061617/60578eac8dcd8c2980166927/html5/thumbnails/14.jpg)
ENVIRONMENTAL RISK FACTORS FOR NTDS
• Established risk factors – maternal folate status – pre-gestational diabetes – maternal use of anti-epileptic
drugs – maternal obesity
• Compelling evidence – maternal vitamin B12 status– maternal hyperthermia
• Proposed, but unconfirmed – exposure to fumonisins– pesticides – hazardous waste sites
maternal characteristics as well as exposures that influence the in utero environment of the developing embryo

Use of Consomic (Chr. Substitution) Mouse Strains
• Treat pregnant mice with Chr. 7 from VPA sensitive strain (A/J) placed on resistant background (C57) with VPA and collect fetuses
• Confirms Chr. 7 as site of sensitivity genes
• Screen candidate genes for SNPs

Next Steps to Understanding Genetic Basis of Susceptibility to VPA-Induced NTDs
•Deep DNA Resequencing of Relevant Regions of the ACSM gene family in SWV and C57 Mice
•Development of ACSM Knockout Mouse Models to be Challenged with VPA Treatment
•Have Obtained ES clones for ACSM4 and Blastocyst Injections are in Progress
•Human Patients From NEAD Study Exposed to VPA in utero with Variable Outcomes will be sequenced for variants in the ACSM gene family
•Multiple candidate genes localized to this region
