PGT’s MTHFR genotyping supports doctors in determining the risk of hyperhomocysteinemia, which is a known risk factor for cardiovascular disease.
Methylenetetrahydrofolate Reductase (MTHFR)
MTHFR gene testing determined that the MTHFR (Methylenetetrahydrofolate Reductase) enzyme catalyzes the formation of 5-methyltetrahydrofolate, the main circulating form of active folate. The absence of active folate leads to accumulation of plasma homocysteine. The 677 C>T polymorphism of MTHFR leads to decreased MTHFR enzymatic activity and elevated homocysteine. The 1298 A>C polymorphism is associated with significant increases plasma homocysteine levels only when in combination with the 677 C>T polymorphism. High plasma homocysteine has been revealed to be a risk factor for atherosclerotic heart disease, myocardial infarction, cerebrovascular disease, and venous thrombosis. MTHFR lab testing It has been reported, associations between the 677 C>T polymorphism and increased risk of fetal neural tube defects in pregnant women, increased risk for methotrexate toxicity, and augmented chemosensitivity of colon and breast cancers to 5fluorouracil.
