Normal allele: TT
Reduces the formation of the active form of folic acid, which is necessary for the remethylation of homocysteine and other DNA molecules. Administration of the active form of folic acid (5-MTHF or L-methyltetrahydrofolate) can significantly improve risk scores for the effects of mutations. Also a factor that moderately increases the need for vitamin B2.
