Methylenetetrahydrofolate reductase C677T mutation, plasma homocysteine, and folate in subjects from northern Italy with or without angiographically documented severe coronary atherosclerotic disease: evidence for an important genetic-environmental interaction.

Abstract excerpt

Moderate elevation of plasma total homocysteine (tHcy) is a strong and independent risk factor for coronary artery disease (CAD). It can result from genetic or nutrient-related disturbances in the transsulfuration or remethylation pathways for Hcy metabolism. A point mutation (C677T; Ala-to-Val) in the gene encoding the 5, 10-methylenetetrahydrofolate reductase (MTHFR) has been recently reported to render the...
