People with a genetic polymorphism, 677C>T, in the methylenetetrahydrofolate reductase (MTHFR) gene have a reduced ability to convert folate to one of its active forms, 5-MTHF, because the methylenetetrahydrofolate reductase enzyme needed for this conversion is less active [21]. By statistical definition, 2-5% of healthy individuals will have a serum folate level of less than 2.5 The usual reference range of serum folate is 2.5-20 ng/mL.
