MTHFR Test- DNA mutation Analysis of Methylenetetrahydrofolate Reductase
Quest Diagnostics test code 17911 is for a DNA mutation analysis of Methylenetetrahydrofolate Reductase (MTHFR). The test determines if a patient has one, two, or no copies of either of the two mutations in the MTHFR gene, C677T and A1298C.
Changes in the methylenetetrahydrofolate reductase gene can lead to certain health conditions. One of them is hyperhomocysteinemia (high blood levels of homocysteine), which is a risk factor for cerebrovascular disease, cerebral vein thrombosis, coronary artery disease, myocardial infarction, and venous thrombosis. At least 40 mutations in the MTHFR gene have been identified in people with homocystinuria, a disorder in which the body is unable to process certain amino acids properly.
MTHFR Gene Mutations: What You Need to Know
The MTHFR gene mutation test, offered by Quest Diagnostics (code 17911), can reveal changes in your DNA that affect how your body processes folate—a key nutrient for many bodily functions. This test checks for two common mutations, C677T and A1298C, and shows if you have none, one, or two copies of these variants. Why does this matter? These mutations can lead to health issues by raising homocysteine levels in the blood, which is linked to heart disease, blood clots, and even complications in pregnancy.
There’s a lot to unpack when it comes to MTHFR mutations. They play a role in conditions like neural tube defects, infertility, and certain cancers. If this sounds overwhelming, don’t worry! Testing is quick—just a blood or saliva sample—and it can provide insights to help you make better health decisions.
How MTHFR Impacts Your Health
Mutations in the MTHFR gene can lower the activity of an important enzyme your body needs to process folate and regulate homocysteine levels. Elevated homocysteine levels are more than just a numerical value; they signal heightened risks of heart disease, stroke, and other vascular complications. For women, these mutations can complicate pregnancy, leading to a higher chance of miscarriage or birth defects like spina bifida.
But it’s not all bad news! If you discover you have an MTHFR mutation, there are actionable steps to take. A healthier diet, supplements like methylated folate and B vitamins, and regular checkups can go a long way in managing risks.
Is the Test Right for You?
Wondering if you should get tested? It’s worth considering if you have a family history of related health issues, frequent pregnancy loss, or unexplained health symptoms like fatigue or migraines. A genetic counselor can guide you through the process and help interpret your results.
The Power of Lifestyle Changes
Even though you can’t change your genes, you can adjust your lifestyle to manage symptoms. Start by eating more folate-rich foods like leafy greens and citrus, and avoid processed foods with synthetic folic acid, which can be harder for your body to use if you have an MTHFR mutation. Regular exercise, stress management, and cutting back on alcohol and tobacco can also help keep your health on track.
Why Future Research Matters
There’s still so much to learn about MTHFR mutations and their impact. Ongoing studies aim to uncover better treatments and more targeted ways to manage the risks. In the meantime, understanding your genetic makeup can empower you to take control of your health.
