The MTHFR Gene Mutation

MethyleneTetraHydroFolate Reductase. At the heart of our genetic blueprint lies the MTHFR gene, a key player in the methylation process that influences the expression of every other gene within our DNA. This gene plays a pivotal role in crucial bodily functions, including intracellular detoxification, bolstering our immune system, RNA synthesis, and much more, making it a cornerstone of our genetic makeup.

A staggering 80% of us carry a mutation in one of the MTHFR gene’s two most critical alleles (C677T or A1298C), which can significantly impair our ability to metabolize folate (folic acid)—the main catalyst for methylation. This reduction in metabolization capacity, ranging from 20% to 80%, can leave individuals more susceptible to inherited health conditions and compromise their detoxification capabilities.

Demystifying the MTHFR Gene

Beyond the elevated homocysteine levels linked with the C677T mutation, there’s a compelling reason to undergo testing: understanding how it impacts your body’s folate usability. Traditional blood tests for folate levels paint a broad picture, encompassing both metabolized and unmetabolized forms of folic acid, without revealing the exact amount your body can actually use. The key to unlocking this mystery lies in the MTHFR test, offering a personalized glimpse into your body’s unique folate absorption based on your genetic profile.

The silver lining? This crucial test is a once-in-a-lifetime endeavor, as our DNA remains constant. It’s advisable for healthcare professionals to routinely check serum folate and vitamin B12 levels, fine-tuning their analysis to account for MTHFR mutations, thus providing a more accurate assessment of usable folate in the body. It’s essential to differentiate between “normal” laboratory levels and “functional” levels—the optimal values that stand regardless of general population data. For those intrigued by the science of achieving ideal folate levels, further exploration is encouraged through dedicated resources on the topic.

This enhanced understanding not only demystifies the MTHFR gene but also empowers us with the knowledge to better manage our health, paving the way for a healthier, more informed future.

Conditions and Symptoms linked to MTHFR mutation

A partial list of conditions, in alphabetical order, linked by research that are associated with MTHFR mutations include:

ADHD, anemia, anxiety, asthma, Autism, blood clots, cancer (various), cognitive developmental delays, depression (Note: Folic acid is a direct contraindication for people that have MTHFR mutations and MTHFR patients should only take a methylated form of folate. Dosage should be calculated based on the individual mutation and blood marker assessment), diabetes, Down syndrome, glaucoma, heart attacks, infertility, microcephaly, migraines, miscarriages, MS (multiple sclerosis), NTD (Neural Tube Effects), peripheral neuropathy, schizophrenia, stroke, etc.
The symptoms associated with these genetic conditions vary greatly depending on the individual and may affect virtually any organ of the body. The most common symptoms include fatigue, brain fog, infertility, gut issues, leaky gut, depression, anxiety, panic attacks and other emotional imbalances, fibromyalgia, chronic fatigue, irritable bowel syndrome (IBS), migraines, blood clotting, developmental delays, seizures, microcephaly, poor coordination, numbness or tingling of hands and feet, and more…
