MTHFR Variants

Meaning

MTHFR Variants refer to common genetic polymorphisms, specifically single nucleotide polymorphisms (SNPs) in the Methylenetetrahydrofolate Reductase gene, such as C677T and A1298C, that can reduce the enzyme’s functional capacity to convert 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate (5-MTHF). This reduction can impair the critical process of methylation, which is vital for hormone metabolism, neurotransmitter synthesis, and DNA repair. Understanding these variants is crucial for personalized nutritional and hormonal support.
