mthfr-geneMTHFR gene mutation… What’s the big deal about Methylation?

Do you have a genetic defect in the MTHFR gene??

Maybe you’ve have a family history of heart attack or stroke or perhaps you’ve suffered through multiple miscarriages.  Have you struggled with chronic migraine headaches or irritible bowel syndrome or depression?  Perhaps your child or a sibling has autism.  What do all these things have in common?  Well, these are just some of the conditions liked to a faulty enzyme called MTHFR.

What’s up with MTHFR?

MTHFR stands for methyl-tetrahydrofolate reductase, an enzyme that is responsible for the process of methylation in every cell in your body.  MTHFR is a common genetic variant that causes this key enzyme in the body to function at a lower than normal rate.  This can lead to a variety of medical problems.  Although there are over fifty known MTHFR variants, the two primary ones are called C677T and A1298.  Your doctor can order a blood test to determine if you have these genetic variants. Better yet, you can order a complete genetic profile yourself through 23andMe.

What’s the big deal about methylation?

Methylation is a core process that occurs in all cells to help your body make biochemical conversions.  When people with genetic mutations is MTHFR are exposed to toxins, they have a harder time getting rid of them which can cause some very serious illnesses.  The methylation process is responsible for:

  • Cellular Repair: synthesis of nucleic acids, production & repair of DNA & mRNA
  • Detoxification and Neurotransmistter  Production:  interconversion of amino acids
  • Healthy Immune System Function:  formation & maturation of red blood cells, white blood cells & platelet production

The 677T variant is most commonly associated  with early heart disease and stroke and the 1298C variant with a variety chronic illnesses, but either anomaly can cause a wide variety of health problems.  The MTHFR anomaly is reported out as heterozygous or homozygous.  If you are heterozygous that means you have one affected gene and one normal gene.  Your enzyme activity will run at about 60% efficiency compared to a normal.

If you are homozygous or have 2 abnormal copies, then enzyme efficiency drops down to 10% to 20% of normal, which can be very serious.   The worst combination is 677T/1298C in which you are heterozygous to both anomalies.  Many chronic illnesses are linked to this anomaly.  Fibromyalgia, irritable bowel syndrome, migraines, chemical sensitivity, frequent miscarriage and frequent blood clots are all conditions associated with MTHFR anomaly.  For a great diagram of more methylation related health problems, check this out:

MTHFR Related Health Problems 

Glutathione is the body’s primary antioxidant and detoxifier.  One of the ways that MTHFR gene mutation can make you susceptible to illness is by lowering your ability to make glutathione.    People with MTHFR anomalies usually have low glutathione, which makes them more susceptible to stress and less tolerant to toxic exposures.  Accumulation of toxins in the body and increased oxidative stress, which also leads to premature aging.

 

Some conditions that may be associated with MTHFR gene mutations

  • Autism
  • Addictions: smoking, drugs, alcohol
  • Down’s syndrome
  • Frequent miscarriages
  • Male & female infertility
  • Pulmonary embolism and other blood clots
  • Depression & anxiety
  • Schizophrenia
  • Bipolar disorder
  • Fibromyalgia
  • Chronic Fatigue Syndrome
  • Chemical Sensitivity
  • Parkinson’s disease
  • Irritable Bowel Syndrome
  • Stroke
  • Spina bifida
  • Migraines
  • Hyperhomocysteinemia
  • Breast cancer
  • Atherosclerosis
  • Alzheimer’s
  • Multiple Sclerosis
  • Myocardial Infarction (Heart Attack)
  • Methotrexate Toxicity
  • Nitrous Oxide Toxicity

Treatment for MTHFR

Fortunately, you can easily be tested for the MTHFR mutation.  If you find out that you have one or more of the gene mutations, you can supplement with methyl-folate  and methyl B12, the active forms of these B vitamins.   You can also supplement with liposomal or acetyl-glutathione, the end product of the pathway.  Glutathione is poorly absorbed so either the liposomal form or a precursor, called n-acetylcysteine (NAC) may be used. Some of my favorites are Thorne Research Methyl Guard Plus and 5-MTHF 1mg and 5mg.

There are prescription medicines, that also contain methyl-folate: Deplin, MetanX, CerefolinNAC are a few.   Methyl B12 can also be given as shots, nasal sprays, and sublingually.  The intramuscular shots are by far the most effective method and must be prescribed by your physician.  The choice of nutrients will vary from patient to patient and should be done under a doctor’s supervision.  There is a bell-shaped optimal curve so you may not feel well with too much or too little of the appropriate supplements.   Other B vitamins, such as riboflavin and vitamin B6 also play an important role.  As you may have surmised, this can be quite complex and I suggest you find a functional medicine trained physician to help you sort through your needs for the different nutrients if you have a chronic health condition related to the gene mutations.  It is not uncommon for patients with these genetic polymorphism’s to be very sensitive to supplementation.

Patients who I recommend screen for MTHFR mutations:

  • Pre-conception care: test both man and woman
  • Mental dysfunction including but not limited to depression, anxiety, irritability, mood swings, schizophrenia, bipolar
  • Infants and children of parents with MTHFR mutations
  • Family members related to someone with MTHFR mutations
  • Elevated folate (not processing to active 5-MTHF due to inability to methylate)
  • Elevated homocysteine (due to low active 5-MTHF and methylcobalamin)
  • Elevated s-adenosylhomocysteine (due to low active 5-MTHF and methylcobalamin)
  • Elevated serum cobalamin (due to inability to methylate cyanocobalamin to methylcobalamin)
  • Elevated methylmalonic acid (due to methylcobalamin deficiency)
  • Patients with syndromes: IBS, Chemical sensitivity, Fibromyalgia, Down Syndrome, Chronic fatigue syndrome
  • Neurological disorders: Multiple sclerosis, Autism, Alzheimer’s, Epilepsy, Parkinson’s to name a few
  • Cancer: family history of cancer or undergoing cancer treatment
  • Cervical dysplasia
  • Infertility
  • Cardiovascular risk: family history of strokes, embolisms, heart attacks, clots, essential hypertension
  • Birth defects: cleft palate, tetralogy of Fallot, spinal bifida, midline defects
  • Drug sensitivities: methotrexate, anti-epileptics, nitrous oxide, anesthesia

If you are interested in knowing more about your genes, you can do multiple gene tests like 23 and me, plus new sites on the horizon.

    My holistic clinic is 99% certain I am MTHFR…because when the dentist and administered ‘lidocaine’ anesthetic it almost killed me.
