Definition

  • Mutations, C677T and A1298C, in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene increase the risk of thrombosis (OMIM# 188050) and other cardiovascular disorders as a result of an elevated plasma homocysteine concentration (OMIM# 236250).

  • Normal values: negative or no mutations are found.

Use

  • Suspected coronary artery disease, homocystinuria, neural tube defects, spontaneous abortion, or MTHFR deficiency

Limitations

  • The results of a genetic test may be affected by DNA rearrangements, blood transfusion, bone marrow transplantation, or rare sequence variations.
