An MTHFR gene test is a medical test that examines variations in the MTHFR gene, which provides instructions for making an enzyme called methylenetetrahydrofolate reductase. This enzyme plays an important role in processing amino acids and breaking down folate, a type of vitamin B9, in the body. Variations or changes in the MTHFR gene can affect how well this enzyme functions, potentially impacting folate processing and increasing the risk for certain health conditions, such as cardiovascular diseases, problems that are present at birth, and some types of cancer. The MTHFR gene test helps identify these variations, which can help in treatment and making lifestyle adjustments to manage associated health risks.
