Congenital heart defects and genetic variants in the methylenetetrahydroflate reductase gene
10 Jun 2005
Abstract excerpt
BACKGROUND: Most non-syndromic congenital heart defects (CHD) are caused by a complex interaction between maternal lifestyle factors, environmental exposures, and maternal and fetal genetic variants. Maternal periconceptional intake of folic acid containing vitamin supplements is reported to decrease the risk of CHD.
