Abstract excerpt
Association between neural tube defects (NTDs) and C677T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene was suspected, because the MTHFR gene codes for a key enzyme in folate metabolism. Its deficiency usually leads to significant reductions in plasma concentrations of folate, vitamin B(12) and methionine, whereas homocysteine levels are increased. We examined folate, vitamin B(12) and...
