BBB Collaborative Research: Genetic Risk Factors for Birth Defects

BBB collaborates with the Birth Defects Research Group in the Epidemiology Branch (EB), investigating genetic and other risk factors for neural tube defects (e.g., genetic risk factors related to folate and vitamin B12), and genetic factors related to risk for cleft lip and cleft palate.

Because low folate status is an important risk factor for neural tube defects, the group conducted the Trinity Student Study, a quantitative traits genome-wide association study to look for genetic variants associated with low folate status in 2,500 students at Trinity College in Dublin, Ireland. The data from this study are being analyzed to identify variants that will be tested for association with neural tube defects.
