I Have an MTHFR Gene Mutation

I had never heard of the MTHFR mutation until almost two years ago when I lost a second child to preterm labor. I wonder how many families can be spared the loss of their children by instituting a routine screening for this not-that-uncommon mutation. A diagnosis and referral to a perinatologist in the beginning of my pregnancy probably would have saved the lives of my son Jacob, born at 22 weeks, and my daughter Madelyn, born at 25 weeks. It is my hope that the information I have gathered here can help save someone else's child.

What is MTHFR?

No, it's not an abbreviation for a swear word...

MTHFR is an acronym for Methylenetetrahydrofolate reductase. It is both the name of a gene, and the name of the enzyme which that gene produces. Individuals with a mutated copy of this gene produce an enzyme that is less effective at breaking down the amino-acid homocysteine. The mutation can occur at one of two sites on the gene. Since we receive two copies of each gene, one from our father and one from our mother, there are a few different possibilities for the disorder. The C667T mutation can be heterozygous, one mutated copy, or homozygous, with both genes having the mutation. The same is true for the A1298C mutation.

Compound heterozygotes have a single mutation at both the C and A locations. A person with the homozygous C mutation can only produce the defective MTHFR enzyme. These individuals are at the highest risk for developing hyperhomocysteinemia - an excess of homocysteine in the blood, especially if their dietary intake of folate is low. High levels of homocysteine damage the blood vessels, leading to an increased chance of developing blood clots, which in turn elevates the risk of deep vein thrombosis, pulmonary embolism, heart attack and stroke.

My son was born healthy and full term after treating my MTHFR.

MTHFR and Pregnancy

A MTHFR mutation may go undiagnosed until a woman has experienced several pregnancy losses. I was not diagnosed until after my second preterm labor and delivery. Some women with this mutation have trouble conceiving or have early miscarriages. In my case, after receiving the diagnosis I was treated by a perinatologist who specializes in high-risk pregnancies. I was given Folgard, a prenatal-with-DHA Vitamin and a low-dose aspirin regimen before trying to conceive and once my pregnancy was confirmed and my beta HCGs were rising I was switched from the aspirin to Innohep, a low molecular weight heparin daily injection. This therapy was a success, and I had my son full term and without complications on October 1, 2010.

What about my child? Do I need to worry for their health?

You took the vitamins and aspirin and heparin, and after nine months of worrying finally have your beautiful baby. But now you wonder, "Does my child have this mutation too?" If you have a homozygous mutation, your child got one of your bad copies of this gene. For heterozygotes, you don't know which copy was passed to your baby. You don't need to worry (but I know you will anyway) just make sure you child's pediatrician knows of the history. Make sure you give your child a children's multivitamin daily plus a DHA supplement for kids and that will be all they need. If you have a daughter, when she decides to have a child she will need to be tested for the mutation. She will have the benefit of foreknowledge and will hopefully avoid the tragedy so many of us had to endure before we received our diagnoses.

UPDATE; I had my daughter tested through 23andme and she has one MTHFR mutation, as well as other mutations that affect her ability to get B12. We now give her a sublingual Methylfolate/B12 tablet each morning and a second Methyl B-12 sublingual after school. I've noticed her behavior improves when she takes the supplements.

Find if you have an MTHFR Mutation or any number of genetic conditions that may affect your health.

I had my daughter and I tested through this summer. I have been learning more about alternative treatments for MTHFR and knowing whether we had other mutations which combine with the health risks seemed to be the next logical step in our path to health. Since our family doctor didn't feel it was necessary to test my daughter at her age (six) this also gave us her MTHFR status. She faired much better that me on the whole, and that is a relief for me. Hopefully, she will never develop health problems related to MTHFR since we are making sure she has the nutrition she needs and avoids exposing herself to environmental toxins from pesticides, processed foods and the like.

As for me, I found that I have several more mutations that elevate my risk for heart disease and blood clots. Knowing this though, will help me take further steps to ensure that I am at my healthiest.

Can you donate blood with an MTHFR Mutation?

I have been donating blood since high school. After I found out about my MTHFR mutation I wondered if I would still be eligible to donate blood. My daughter Madelyn required multiple transfusions during her short time with us, so I really wanted to donate in her memory. After my iron levels were back up to normal I took a trip to the local Red Cross Donation Center. I spoke with the nurse there, and she told me that I could donate whole blood as long as I wasn't taking any blood thinners, eg. heparin, lovonox, innohep. The aspirin was ok to take for donating whole blood, but not if you want to donate plasma. It feels good to donate blood, even though I end up tearing up each time, thinking about my little girl.

MTHFR and now EDS III as well, yikes!

Since I got my raw DNA data from 23andme, I found out you could run that through a program called Promethease for more health reports. I first addressed the mutations I found that were homozygous figuring those would affect me most. After those, I moved on to heterozygous mutations. One I found had been implicated in something called Ehlers Danlos Syndrome IV. After a quick google search, I learned that a lifetime of strange health issues had all been due to EDS.

So is there any good news? Every cloud has a silver lining.

Believe it or not there are some benefits to this mutation. There is a decreased risk of both colon cancer and leukemia. In fact, scientists are studying the relationship between MTHFR and cancer risk to one day develop a treatment for cancer therapy.

@Lori williams

So sorry about your issues with MTHFR. It definitely is a challenge. I have not heard of any connection between neuropathy and MTHFR, but it is possible.

There are many causes of peripheral neuropathy, including diabetes, chemo-induced neuropathy, hereditary disorders, inflammatory infections, auto-immune diseases, protein abnormalities, exposure to toxic chemicals (toxic neuropathy), poor nutrition, kidney failure, chronic alcoholism, and certain medications –

I hope you can find a good doctor who can rule out the improbable causes and pinpoint what is causing your neuropathy. It is painful and affects your activities. If you find out what it is, let us MTHFRs know please. Best wishes.

Lori williams on January 27, 2019:

I have recently been diagnosed with 2 mutations. I have had 7 problem pregnancies , 5 live births and have unexplained neuropathy in both feet. Do you know if the neuropathy could be caused by it? And can it be reversed or repaired?

Elayne from Rocky Mountains on January 19, 2019:

@Lauren Neuenschwander

So sorry about your miscarriages and that you also have the mutation.

I have been taking Deplin 15 mg daily and it seems to help. Have you tried it? I feel very lucky that I was able to have my children with MTHFR. We have one granddaughter who was born with spina bifida and not sure if that is related.

Here is a link that might help:

I hope you are able to find a doctor who understands MTHFR and will help you build your DNA to what it needs to be.

It is hard to find a doctor educated on this subject.

Praying you will find the help you need soon.

Lauren Neuenschwander on January 15, 2019:

I have had 3 miscarriages around 9-10 weeks. I havent had any live births. Im 33 and my husband is 34. We just found out we BOTH have the c677t homozygous mutation. I feel so lost and get so many different answers from the 4 fertility specialists ive seen. If you have any advice I would love it. For whatever reason we havent been able to concieve at all the for the last 13 months.

Katie Q on September 02, 2018:

My 7 yr old son has a double MTHFR C677T mutation too. Our doc recommended a supplement called Methyl Factors 10 drops twice a day. Though there seems to be folic acid in it, so I'm not sure about that part.

Keland on August 29, 2018:

I just found out my 5 yr old son has a double MTHFR C677T mutation...

I have no resources for help on diet, supplements ,etc..

I understand there's no protical as each personnis different, but any advice would greatly appreciated..

Elayne from Rocky Mountains on August 29, 2018:

So sorry for the loss of your babies. I have had three miscarriages and have four live children and 12 grandchildren. My daughter also has MTHFR and was only able to have one child. I take Deplin 15 mg daily and it is very expensive. I also take a baby aspirin every day. I am wondering if I need to do more to prevent heart attack or stroke. Many doctors are not up to date with the things you mentioned. Best wishes!

Kristen on August 28, 2018:

How did your mutation impact whether or not you gave your babies the K shot?

I have MTHFR and trying to figure out if we give our baby the k shot at birth..

Lenore on September 13, 2017:

Thank you for sharing your story--it gives me hope! I was just diagnosed with homozygous C677T and had an early miscarriage earlier this year. Thank you for sharing your treatment and the outcome of a successful pregnancy--it encourages me in my own fertility journey. I am so sorry for your losses.

Angela on September 05, 2017:

I have a strong family history of spina bifida/anencephaly, miscarriage, heart disease, endometriosis/uterine cancer, diabetes, unexplained allergies that worsened with stress, depression/alcoholism, and hypermobility. Two years ago, I became violently ill with what appeared to be chronic pseudoanaphylaxis. No doctor from my PCP to the docs at the Mayo Clinic could tell me what I had, and medications made me worse. I used 23andme to discover I was C677T homozygous. I also am suspected of having HEDS, although the geneticist said he didn't know which mutations to look for. I found an endocrinologist who would prescribe Deplin. I've told every doctor I saw during my illness that Deplin, hydroxycobalamin, and electrolytes were the answer. I am in excellent health now.

Any doctor can order an MTHFR blood test. At LabCorp, it is $200 without insurance. My insurance covers it. I've had all my children tested. It ended up being cheaper than 23andme.

Elayne from Rocky Mountains on March 25, 2015:

I just found out I have the MTHFR mutation - heterozygous A1298C and have had a lifetime of symptoms including anxiety, depression, insomnia and very difficult births of my four children. I did have one miscarriage, but it was very early in the pregnancy. My two sisters have suffered from the same type of symptoms as mine. I suggested they have the blood test. I am anxiously awaiting their results. I hope more people are becoming aware of this mutation. I am taking Deplin and feel better on it. Too bad I didn't learn about this until I was in my 60s.

anonymous on November 26, 2012:

First I want to say that I understand what it is to lose babies or to miscarriage, we lost five total and have six kids. I am sorry for your loss. It helped a lot to name and baptize them by desire. My story cd help many. It starts with me being an engineer and marrying an engineer. We first miscarried 4 years into our marriage; I was perhaps 2.5 months pregnant. Then when we tried to have more, we kept miscarrying. This was devastating to me, esp. since my siblings had no problem at all. It took me many years to talk about it. Then somewhere around then, with many abdominal symptoms, I went on a GF diet. When I was on this diet I was able to conceive, and the Dr. put me on progesterone. The 3rd child we had, I stopped taking the progesterone because a Vet friend scared me to death about it (But now I think itâs safe point is, we had 4 more without progesterone, and donât know if we needed it or not. At some point, stopped the GF diet, and still had kids.(Some who miscarry STOP when they go on a GF diet.)). So fast forward 22 years with our kids to today, and we discovered 5 yrs ago our youngest was a Celiac. Eventually everyone was tested for Celiac (simple blood test ask for full panel and IgA), then we found 2 more kids with Celiac, but THEY werenât the hyper ones, so we did further testing with Dr Kenneth Fine in Dallas through Entero Labs and found out other 3 were Gluten Intolerant, and 4/6 plus both parents dairy intolerant. As far as Iâm concerned, the jury is out on the two who can supposedly have dairy, as if they have NO IgA then their test cd have come back that they can have dairy when their bodies may actually be immune also to the dairy. After all, both of their parents are dairy intolerant. I believe in medical tests. Two of us also cannot have soy. Soy, dairy, and gluten are all very similar proteins, some experts say if you canât have gluten, then you sd abstain from all three. (Canât find the link on that, it was utube) So, since 5/6 kids are ADD or ADHD, we went to the ASD center in St Peters MO. We went through a battery of blood tests, including genetic. They routinely check for MTHFR and so I have it (C677T and ?? I have to find test but I am E2/E3.) and my 4th son who is C677T and A1298 (He is E2/E2), one son who is C677T homozygous (E2/E2) and my 3rd son who has none, and two daughters who also have MTHFR, both of whom are E2/E2 for broad beta vascular disease. Theytold us at ASD center, if have MTHFR, then we are poor methylators , and we are not protected from mercury. My theory is that since all of my kids were vaccinated starting year 1990, that all that mercury turned on the gene for Celiac. We also dropped and broke 2 mercury thermometers. They told us we can no longer eat tuna and that we were exposed recently. We are not sure from what, although I did figure out that plastic, and perhaps straws, and a source, I wish there were some studies to show that. They told us to take Methyl B-balance and I found that the elements in there can be purchased separately, and I tolerate the ones separate not the methyl b-balance.

There must be a filler in there I can not tolerate. But taking these chelates the heavy metals and is like a "pre-digested form of folate", which apparently our bodies need and can't "digest" the regular folate? But, to tell you, having this I was at higher risk for having children with downs, preemies, cleft palate, spina bifida (for having the MTHFR) however, I religiously took folic acid during all my child bearing years and I also had heard that women in other countries take kelp to prevent birth defects and I took this as soon as I learned I was pregnant. I feel that things would have turned out much worse if I hadn't done those two things. Kelp powder (non-irradiated) can be put in salt shaker half and half with salt. Hope this info can help someone. We were at higher risk, but I took the folic acid preventatively, and all our children were free from those things. I am most concerned about son #3 who is C677T double and he is very sedentary and that apparently goes along with it, or can. He doesnât seem to have desire to do anything, and has not really had any passions in his life. Also what goes along with this is no executive functioning skills, which he has an IEP for, but it is really difficult. Any insight wd be appreciated.

I suffered a PE at age 43. I have both c677 and a1298. Unknown if they are homozygous or compound heterozygous. Both parents died. Mom at 58. Dad at 64. Lost twin sister at 41. My 6 year old son tested for c677. They say he is a carrier. I am on warfarin for life. Do I need to be on vitamin b6, b12, and folic acid as well? Will the vitamins affect the warfarin?

I had a miscarriage at 10 weeks and 3 days and Lost my baby. I found our after my D&C that my miscarriage was a result in Homozygous. My Dr. informed me I had both Homozygous and Heterozygous. She didn't specify what type or anything. My fiancé and I are trying to conceive again now that Ive gotten my first menstrual cycle and have been taking 1mg Folic acid, 2 Medinex tablets and a B6 vitamin a day. Me and my fiancé are terrified to lose another baby. Any suggestions? I lost the baby on August 27th, one day before my birthday, I went in for my first ultrasound and was told the baby had no heart beat but I had no signs of any problems, It was almost too hard to believe...

Jackie Block (author) from SE Michigan on October 08, 2012:

@anonymous: I am very sorry for your loss, Michelle. I, too, was upset over my diagnosis. I was seen by a perinatologist after my second preterm labor and the MTHFR was discovered. He explained that the Preterm labor was due to blood clots that formed in the small blood vessels that feed the placenta. Both my losses were due to placental abruption, caused by the clots. For my last pregnancy he put me on a blood thinner, Innohep, and I had no placental problems and carried full term. My family will keep yours in our thoughts and prayers.

anonymous on October 08, 2012:

I had three miscarriages...had IVF and got pregnant with twin. At 23 1/2 weeks I went into preterm labour. I lost my daughter. I was able to carry my son for an additional two weeks and he was born at 25 1/2 weeks. I just found out I am a heterozygote for C577 and A1298. I am so upset. For the author of this article did anyone every indicate why you went into preterm labor?

anonymous on September 26, 2012:

I'm going through ivf now, and have high nk cells and MTHFR. I'd like to be able to give back in some way, and was hoping to be able to donate eggs after we're successful with our journey. Will the MTHFR preclude me from this?

@getpregnantaftermiscarriage: As someone who had three pregnancies in two years, I can attest to the strain, both physically and emotionally. It is important to give your body time to heal. Your doctor can advise you on how long you should wait before trying again.

@anonymous: Found out I also have MTHFR. Tested positive for both C677 alleles. Our three surviving boys have one or two damaged alleles as well. I would love to find a doctor who is knowledgeable about how to improve quality of life. It appears we don't have any of the major problems that can come from having this anomaly, but there are still problems I would like to solve! Can't take B vitamins or 5 THF. They seem to exacerbate symptoms. Couldn't figure out why I got more tired than anyone else in sports, and now I know. It will help me educate my boys and give them good nutrition during their sporting activities. I am very concerned about how to help one of my boys, and my husband deal with stress. Homeopathics, herbs, would be more of a help than prescriptions. If anyone has a good doc, let me know!

I had 5 preterm losses between the 3 live births of my boys at around 14-17 weeks. My husband and I went in for Karyotyping which we could only do because he worked for the lab. The tests came back great. It wasn't until a week ago that we found out he tested heterozygous for the MTHFR C677 allele mutation.

This has affected my husband's ability to deal with stress, his ability to rid his body of toxins, his ability to fight free radicals, his digestion absorption...and it could be damaging his heart and vessels. I am still finding out more. This is a breakthrough in his family and can definitely be a factor if people are having infertility issues, early heart problems, high homocysteine levels, stress they can't seem to handle, digestion issues, etc.

People who have this anomaly can be especially prone to toxicity since their bodies cannot detoxify well and can have problems with heavy metals - particularly mercury. The more I find, the more things make sense. FINALLY! Just getting the doctors on board with me is going to be the trick!

anonymous on July 25, 2011:

I'm 31 and I have learned, following a two stroke I have failed very badly that I end this homozygous mutation is the only reason found. In France, no doctor is able to explain this disease, I had to consult a hematologist. I must check my homocysteine ââand stay on aspirin and folic acid. I must not drink alcohol, soda, be careful with cholesterol, not smoking ... It's very hard to learn such a thing overnight. For now, I do not want children, and risk losing a 3rd stroke makes me too scared. Sorry for my english ;)
