Vitamin B12 or cobalamin is an essential nutrient with important roles in DNA synthesis, repair and methylation. It is also required in the one carbon metabolism pathway to reduce plasma homocysteine concentrations. Several epidemiological studies have indicated that genes and metabolites of the B vitamin-mediated one-carbon metabolic pathway are associated with chronic diseases. This short review describes polymorphisms in the MTHFR, FUT2 and TCN2 genes which have been implicated in cardiovascular diseases and neural tube defects amongst others.
