MTHFR gene is in charge of Methylenetetrahydrofolate reductase (MTHFR) an enzyme responsible for folic acid metabolism in the body. In this article weâll look at the function of this enzyme, why itâs important for fertility and the standard treatment for MTHFR mutation. If you test positive, read on, if you test negative, stick to recommended dose of 800 micrograms of folic acid per day. 2  If you tested positive for MTHFR gene polymorphism you will need follow the treatment for MTHFR mutation: start taking 1-5 mg of folic acid a day. 3  Methylated form is best (5-MTHF).
If the MTHFR mutation test is negative, then the C677T and A1298C mutations were not detected and the tested person's elevated homocysteine level is likely due to another cause. Other, more rare MTHFR genetic mutations will not be detected with typical testing.t may be ordered if a person has a close relative with known MTHFR genetic mutations, particularly if that person also has elevated homocysteine levels. MTHFR C677T and A1298C gene mutations are the most common and the ones that are typically tested.
