This site has been created to spread the word about the MTHFR genetic mutation, the symptoms, tests, and treatments. All things MTHFR, but specifically A1298C since I am homozygous for A1298C. I should have named this website "methylation" awareness instead of MTHFR awareness because I have discovered that there is much more that can go wrong besides just MTHFR. However the MTHFR gene is the one I found out about first and is crucial to health. This website is a place to gather and distribute MTHFR information and share my story so that hopefully I can help others.

There is actually a lot of MTHFR information on the internet. In fact, so much info that it can be overwhelming for someone who has just found out they have this mutation and wants to know what it means. Unfortunately due to the relative newness of this discovery there isn’t enough research out there to have general consensus on how to treat MTHFR mutations, but over time this will become more clear. Just hang in there, and don't get frustrated! There's a lot to learn, but if you have this mutation you should feel better even if all you do is take some basic standard supplements.

In my free time I create jewelry to raise money to help me to treat my MTHFR. Please visit my online store! www.shenandoahdesigns.etsy.com

The MTHFR genetic mutation, or polymorphism was first discovered as a result of the human genome project (C677T in 1995 and A1298C in 2001). The gene produces the MTHFR enzyme, and people who have this mutation have a reduced ability to process folic acid/folate into something their body can use.

MTHFR (Methylenetetrahydrofolate Reductase) is the name of the gene and the enzyme that plays an essential role in processing the folate we eat into a nutrient our bodies can utilize. People who have MTHFR mutations have an interruption in the “Methylation Pathway." Methylation affects more than 20 different processes in our bodies and when methylation is interrupted, many many essential body functions are disrupted. This can be worked around by taking the nutrient as supplements that cannot be made because of the missing enzyme. In the case of the A1298C mutation, where there should be an Adenine it is switched to Cytosine.

According to Dr. Lynch, these are the functions of methylation: 

Turn on and off genes (gene regulation)
Process chemical and toxins (biotransformation)
Build neurotransmitters (dopamine, serotonin, epinephrine)
Process hormones (estrogen)
Build immune cells (T cells, NK cells)
DNA and RNA synthese (Thymine aka 5-methyluracil)
Produce energy (CoQ10, carnitine, ATP)
Produce protective coating on nerves (myelination)

Prevalence - MTHFR mutations are very common. 20-40% of caucasions have one copy of the mutation. 4-14% have two copies. Somes statistics I have seen says 40% of people have one copy, and 30% have two copies. Just because you have the mutation does not mean you will show symptoms or develop conditions associated with MTHFR. Why? Because there are other mutations that could factor into things, and also environmental factors. This is big. People with MTHFR have a reduced ability to eliminate toxins and heavy metals, so the cleaner their environment, the better. This also explains why two people can have the same mutation and not be affected equally.

Folate is essential for cell growth and reproduction, the breakdown and utilization of proteins, the formation of nucleic acids, red blood cell maturation, and a variety of CNS reactions. Both folic acid and dihydrofolate are not biologically active forms of folate, but are essentially pro-drugs, and must undergo enzymatic transformation to L-methylfolate in order to be used by cells, and unlike other forms of folate, L-methylfolate readily crosses the blood-brain barrier for use in the CNS. It is impossible to get L-methylfolate from food. One has to get L-methylfolate through supplementation.
