Abstract excerpt
BACKGROUND: A 28-bp repeat polymorphism in the 5'UTR of the thymidylate synthase (TYMS) gene represents a candidate risk factor for neural tube defects (NTDs) due to involvement in folate-dependent homocysteine metabolism. Non-Hispanic, white, U.S. citizens carrying at least one 2x 28-bp repeat allele have recently been shown to be at a four-fold increased risk of spina bifida (SB). We investigated the...
