MTHFR

Methylenetetrahydrofolate reductase (MTHFR) is an enzyme encoded by the MTHFR gene and has significant implications in the field of pharmacogenetics. This enzyme plays a critical role in the folate metabolism pathway, which is integral for processes like DNA synthesis and repair, as well as methylation. Variants of the MTHFR gene are associated with altered enzyme activity, which can, in turn, affect drug efficacy and toxicity.
