Gather together some MTHFR patients and start talking about what ails them. There’s a laundry list of associated illnesses for people with methylation defects and those illnesses do present among MTHFR patients. Autism, cancer, heart disease, fibromyalgia, infertility and recurrent miscarriages, Parkinson’s disease, polycystic ovarian syndrome and stroke are just a few of the chronic conditions where MTHFR gene mutations have been identified as a contributing factor. So any doctor who tells you that MTHFR isn’t a big deal either doesn’t know what he is talking about or is lying through his teeth. Because that inability to detoxify that I’ve been talking about doesn’t just apply to household chemicals, medications and foods that you’re allergic to. It also applies to toxins like viruses, bacteria, fungus and parasites, which we are literally plagued with. And this is where the health problems start to come into the picture. If you haven’t been tested for MTHFR it’s probably because you haven’t gotten sick (yet).

It is important to remember that a methylation defect does not usually cause health problems all by itself. As Dr. Kendal Stewart of NeuroSensory Centers of America explains in his methylation overview:

Most health conditions in society today are multifactorial in nature. In essence, there is an underlying genetically determined risk that requires a significant infectious or environmental “trigger” to initiate the process….if an individual has enough mutations or weaknesses in their methylation pathway, it may be sufficient to cause the multifactorial disease by itself, as methylation cycle mutations can lead to chronic infectious diseases, increased environmental toxin burdens and have secondary effects on genetic expression.

His linked paper is very interesting and I strongly encourage anyone dealing with methylation issues to read it for an explanation of how these issues all tie together. As he notes in his excellent series of podcasts about autism and contributing factors, we’ve all been exposed to toxins. Most human beings have some latent germy junk lying dormant in our systems just waiting for that moment of trauma or period of suppressed immunity to rear their ugly heads. Proper treatment of chronic health conditions cannot occur without exploring all possible causative factors. And I’m not sure how well-known this information is among your average doctors and patients.

I will be exploring the subject of methylation-related health conditions in this new series here on MTHFR Living. We will explore not just neuro-immune diseases but also other related illnesses and health conditions.  If you feel overwhelmed by all of this and perhaps a little down on yourself for having these mutations, please don’t. Consider the fact that our environment has become increasingly more toxic since the Industrial Revolution. Children are exposed to dozens more vaccines at an earlier age today than they were in 1983. Our food sources are less clean and have fewer nutrients than they once did. Viruses and bacteria are pervasive, even if they exist simply as latent infections that act together to complicate things. I’ve recently updated the resources page on this site to include informational websites on some of these ‘root causes.’ If you’re having chronic health problems it is essential to get to the bottom of what is causing them. We cannot blame everything on MTHFR and other gene mutations.

Some recent pieces of media that I’ve come across in my research will be wonderful for allowing health practitioners to explain these factors to you. These people are either experts in this area and/or see this multifactorial causation with their patients or in their research on a regular basis. The first item is a great lecture by Dr. Randall Tent of Diverse Health Services in Novi, Michigan. The first hour of this lecture focuses on the story of how SV40 was introduced to millions of people with the polio vaccine. I have read quite a bit about SV40 and the most important thing I learned, especially after reading The Virus and The Vaccine: The True Story of a Cancer-Causing Monkey Virus, a Contaminated Vaccine, and the Millions of Americans Exposed (St. Martin’s Press 2004), is that we are not safe. This history proves that government health agencies cannot be completely trusted to protect the people and balance the interests of the human population with those of the pharmaceutical companies. The corruption and incompetence demonstrated in this book will astound readers.

Contrary to claims that exposure to the virus was limited and that it no longer has any bearing on the health of our population, SV40 is still being discovered in people today. It is found in people who are too young to have received the contaminated vaccines. The virus is, in fact, present in human cancers and it “disrupts critical cell cycle control pathways” (Vilchez, Butel 2004). A polyoma virus, SV40 is tiny and was not killed during virus inactivation in the making of the polio vaccine. Nine new human polyoma viruses have been discovered sine 2007 with one of these being linked to a lethal form of skin cancer. It has been proven that viruses cause cancer and the study of these viruses led to discoveries about the workings of cellular oncogenes. These viruses may not be what Dr. Janet Butel calls “complete carcinogens” but they play a strong supporting role in tumor formation, particularly during periods of weakened immunity.

So if viruses can cause cancer, what else can they cause? And what viruses are we talking about here? The cancer viruses discussed in the aforementioned studies include Epstein–Barr virus (EBV), hepatitis B virus (HBV), hepatitis C virus (HCV), human papillomavirus (HPV), human T-lymphotropic virus Type 1 (HTLV-1) and Kaposi’s sarcoma-associated herpesvirus (KSHV). If you’re short on time, jump to the second half of Dr. Tent’s lecture and listen to the case studies of patients and their symptoms and the root causes he discovers. He runs a viral panel on his patients that includes tests for EBV, cytomegalovirus (CMV), herpes 1 (HSV-1), herpes 2 (HSV-2), herpes 6 (HHV6), herpes antibodies (HSV), parvovirus B19 and thyroid antibodies. His patients have complained of conditions like lupus, multiple sclerosis (MS), fibromyalgia, arthritis, muscle aches, muscle spasms, night sweats, headaches, numbness, Bell’s Palsy, blurry vision, tinnitus, sinusitis, food allergies, digestive issues, hives, encephalomyelitis, chronic pain and swelling. Tent discovered viruses in most of his patients.

Dr. Stewart also talks about viruses as co-factors in his patients, who are being treated for conditions like autism spectrum disorders (ASD), headaches, ADD/ADHD, vertigo, Alzheimer’s, dementia, MS, fibromyalgia and chronic pain. So far I have listened to his first three podcasts, which mention sources of inflammation like viruses, fungus, parasites, spirochetes, vaccines, antibiotics, yeast and bacteria, which contribute to what he calls “Neuro-Sensory disorders.” Among these he mentions HHV6, streptococcus, parvovirus, varicella zoster virus (VZV) and other herpes simplex viruses (of which there are at least 24). I encourage a listen to the podcasts even if you aren’t dealing with autism; just as Dr. Amy Yasko’s methylation work can benefit everyone, so can Dr Stewart’s work on the causative factors of neuroimmune disease. Any work related to ASD is significant for people suffering from chronic neuroimmune diseases because of the work of Richard A. Van Konynenburg, Ph.D., who drew parallels between chronic fatigue syndrome and autism.

The causative effects of biological toxins like viruses and bacteria are also supported by other research in the scientific community. A 2010 study found that chronic bacterial and viral infections are involved in the progressive chronic diseases discussed in this post, along with others that I have not mentioned. EBV has been linked to systemic autoimmune diseases (SADs) like rheumatoid arthritis (RA), systemic scleroderma (SSc) and systemic lupus erythematosus (SLE). Another study found the EBV, CMV, HHV6 and HHV7 viruses to be strong pathogenic triggers for MS. Hashimoto’s Thyroiditis may be caused by the human herpes virus. Parvovirus B19 has been linked to miscarriages, rheumatoid arthritis and SLE. These are just a few samples pulled from the available literature.

So what does all this have to do with MTHFR? Dr. Stewart talks about a genetic predisposition to chronic health problems like ASD. Certainly a discussion about the relationship of MTHFR to each illness is outside of the scope of this blog post. But put very simply, pathogens like viruses and bacteria cannot be effectively killed and eliminated when methylation is impaired. Gut problems, which are common when people are not detoxifying properly (usually due to a decrease in glutathione levels), lead to a weakened immune system, which triggers the re-activation of latent viruses and bacteria. So in the same way a disease is caused by many factors, methylation defects contribute multiple causative factors to chronic health conditions.

I hope you will join me in this new series as we explore our various ailments. I will delve further into some of the autoimmune and neuroimmune disorders mentioned in this post in more detail as the series progresses. In the meantime, if you are suffering from chronic illness or unexplained symptoms, it may be a good idea to speak to a knowledgeable doctor about potential viral, bacterial and other biological causes and the appropriate testing.

    I just recently was diagnosed with MTHFR. As an OB nurse, I’d definitely heard of MTHFR but didn’t completely understand it. After years of infertility attributed to PCOS and one miscarriage, I decided to seek help from a Naturopathic Doctor. She’s the one who found this gene mutation and suggest various lifestyle changes and supplementation. I am in awe of what I’m reading here. The things my doctor discussed with me are making so much more sense now. I never realized how MTHFR could affect so much. I feel so grateful to have found your website so I can learn more about this new diagnosis. Thank you so much for this valuable information.

    How can I find a dr in my area that knows about this. I find that I have researched and know more about this than any dr I’ve met. They all look at me like I’m crazy.

      Hi Michelle,

      Dr. Lynch does have a list of physicians, but if you’re like me and you’ve done more than 1 week of research about MTHFR, you will find that you know more than most doctors in your area. I would buy Dr. Lynch’s new book, Dirty Genes. Read it and do your own research. Then find a doctor who will respect you when you bring information to the table. That’s what we’re doing for my husband.

      Hi Angela, my understanding is that yes, you still have it. When I was tested they looked at the different antibodies.

      This explains it a bit: https://labtestsonline.org/understanding/analytes/ebv/tab/test/

      I do not have expertise in this area but anectodally I have heard of latent EBV causing health problems. The extent to which those can be correlated to current symptoms and issues seems to be lacking but perhaps someone else with more experience can weigh in. Many, many people will test positive for having had EBV earlier in life…I did and I don’t remember having mono.

    Can anything help with the spasticity attacks? Great post, taken me 2 years of digging to even understand what you mean 🙂 but bang on. Just suffered a “relapse” d’oh genuinely thought I’d smashed it with removal of fungus ridden breast implants ( funghi reactivating ebv of course) and lymph nodes caked in silicone but it appears these buggars love a challenge! Rituximab?!
