Names

Common Name: MTHFR Type: Gene
Chromosome: 1 (NC_000001.11) Locus: NG_013351.1 (MTHFR)
HUGO Symbol: MTHFR Full Name: methylenetetrahydrofolate reductase (NAD(P)H)
Exons: 12 Introns: 11

Description:
MTHFR is a critical metabolic enzyme in the folate cycle. Folate functions in multiple coenzyme forms in the redox processing of one-carbon unit transfer reactions. The encoded protein catalyses the reduction of 5,10-methylene tetrahydrofolate (THF) to 5-methyl THF, which is in turn demethylated to complete the folate cycle. The procedure results with one carbon being donated to the homocysteine molecule in the methionine cycle to generate methionine. Metabolites of the methionine pathway are essential for the methylation of many cellular compounds, including DNA and the allosteric inhibitor of MTHFR. Genetic variation in this gene influences susceptibility to occlusive vascular disease, neural tube defects, colon cancer and acute leukemia, and mutations in this gene are associated with methylenetetrahydrofolate reductase deficiency. Polymorphisms in this gene associated with avascular necrosis in sickle cell patients.

Synonyms: 5,10-methylenetetrahydrofolate reductase (NADPH)
