A common mutation, C677T, in the methylene tetrahydrofolate reductase gene (MTHFR) reduces the activity of MTHFR and increases total homocysteine levels in plasma. Increased homocysteine levels are reportedly associated with high serum uric acid levels.
Some people have a genetic mutation in 1 or both of their MTHFR genes. People with a mutation in 1 MTHFR gene are are said to be heterozygous; if mutations are present in both genes, the person is said to be homozygous or compound heterozygous for the mutation(s).
D68. 51 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM D68. 51 became effective on October 1, 2021.
There are two common types, or variants, of MTHFR mutations: C677T and A1298C. These gene mutations are relatively common. In fact, in the United States, around 25% of people of Hispanic descent and 10–15% of people of Caucasian descent have two copies of C677T.
If a person has two copies (homozygous) of MTHFR C677T, or has one copy of C677T and one of A1298C, then it is likely that elevated homocysteine levels are due to these inherited mutations, or that the mutations are contributing to them.
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
There are two common MTHFR mutations, known as C677T and A1298C. The term MTHFR stands for methylenetetrahydrofolate reductase. MTHFR is an enzyme that breaks down the amino acids' homocysteine and folate. Homocysteine is an amino acid that works to maintain the body's cells.
Homocystinuria due to MTHFR deficiency is a genetic condition that results from poor metabolism of folate (also called vitamin B9), due to a lack of working enzyme called MTHFR. The gene that tells our body how to make the enzyme is also called MTHFR.

Outlook. Methylenetetrahydrofolate reductase, or MTHFR, is an enzyme that breaks down the amino acid homocysteine. The MTHFR gene that codes for this enzyme has the potential to mutate, which can either interfere with the enzyme’s ability to function normally or completely inactivate it. People have two MTHFR genes, ...
There are two common types, or variants, of MTHFR mutation: C677T and A1298C. Mutations in MTHFR genes occur in approximately 25% of people of Hispanic descent and 10–15% of North American Caucasians.
These mutations in rare occasions lead to high levels of homocysteine in the blood, which may contribute to numerous health conditions, such as: birth abnormalities. glaucoma. mental health disorders. certain types of cancer. In this article, we look at MTHFR mutations in more detail, including related health conditions, diagnosis, ...
Conditions that researchers have associated with MTHFR gene mutations include: homocystinemia, which is the term for abnormally high levels of homocysteine in the blood or urine. ataxia, a neurological condition that affects coordination. peripheral neuropathy, a neurological condition that damages the nerves.
Women who test positive for an MTHFR mutation may have an increased risk of preeclampsia, blood clots, recurrent miscarriages, or giving birth to a baby with congenital disabilities. Multiple studies have been done to determine relationship between the mutation and pregnancy complications, but the data is insufficient in their conclusions.
Having an MTHFR mutation does not affect everyone in the same way. People who have one or more MTHFR variants may have higher-than-normal levels of homocysteine in their blood or urine.
Mutations can occur in one or both genes. Having a parent or close relative with an MTHFR gene mutation can increase a person’s risk of inheriting the same variant. People who have two parents with mutations have an increased risk of having a homozygous MTHFR mutation.
C677T or rs1801133 is a genetic variation—a single nucleotide polymorphism (SNP)—in the MTHFR gene. You get one copy of this gene from your mother and one from your father, so there are two possible copies that can be either “normal” or “mutant”. C…T stand for the bases that you actually have.
Avoid folic acid blocking drugs such as birth control or Methotrexate. Avoid drugs which increase homocysteine such as Nitrous Oxide (most used in dentistry) Avoid antacids as they block absorption of vitamin B12 and other nutrients. Begin understanding which of your symptoms may be related to the C677T MTHFR mutation.
If you are pregnant, find an OB/GYN or midwife who is knowledgeable about MTHFR. Eliminate Gluten from your diet – especially wheat. Eliminate or reduce Dairy from your diet. If you must have dairy, use Goat milk. Sauna or sweat somehow (epsom salt baths, sports, yoga..) at least once to three times a week.
Adequate intakes of folate help reduce the risk of neural tube defects such as spina bifida or anencephaly. A folate deficiency can also cause other birth defects such as heart and limb malformations. Folate is needed for DNA replication, therefore without folate the fetus’ cells are unable to grow properly.
If you get lots of dark green leafy veggies, legumes and other food sources of natural folate then you’re probably already getting good methylfolate. If your diet isn’t up to scratch, then supplementation can be useful, ...
According to SNPedia, which compiles research on genetics, C677T mutants have been shown in at least one research study to have an increased risk for: These are some recommendations for the two types of mutations heterozygous (1 copy of C677T) and homozygous (2 copies of C677T) MTHFR mutations.
The methylenetetrahydrofolate reductase ( MTHFR) gene contains the DNA code to produce the MTHFR enzyme. This test detects two of the most common mutations. When there are mutations or variations in the MTHFR gene, it can lead to serious genetic disorders such as homocystinuria, anencephaly, spina bifida, and others.
MTHFR C677T and A1298C gene mutations are the most common and the ones that are typically tested.
If the MTHFR mutation test is negative, then the C677T and A1298C mutations were not detected and the tested person's elevated homocysteine level is likely due to another cause. Other, more rare MTHFR genetic mutations will not be detected with typical testing.
The two MTHFR variants are called C677T and A1298C, and individuals can inherit one or both variants. These SNPs result in changes in the DNA (or mutations) that are associated with decreased MTHFR activity and increased homocysteine levels in the blood, which may increase the risk of premature cardiovascular disease (CVD), ...
One cause of that could be a mutation in the MTHFR gene, causing homocystinuria. While at least seven unique MTHFR mutations have been found in people with homocystnuria, there are two relatively common DNA sequence variants, known as single nucleotide polymorphisms (SNPs), that are tested.
The MTHFR enzyme is critical for metabolizing one form of B vitamin, folate, into another. It is also part of the process that converts homocysteine into methionine, an important building block for many proteins. If someone has increased levels of homocysteine, that means the body is not processing it properly.
Approximately 5-14% of the U.S. population is homozygous for C677T, meaning that they have two copies of it. There is some ethnic variability in the frequency, with the highest being in those of Mediterranean ancestry and the lowest in those of African ancestry.
Those with a heterozygous MTHFR gene mutation (C677T) may lose roughly 40% of their enzyme activity, and those with a homozygous MTHFR mutation may lose up to 70%. Today, science has proven that our body has a mechanism capable of silencing “bad genes” or regulating gene expression. This process is called methylation.
Below is a partial list of MTHFR symptoms and conditions in alphabetical order: Addictions. Alzheimer’s.
The MTHFR Gene Mutation – Methylenetetrahydrofolate Reductase (MTHFR) is critical in the function of DNA methylation, a complex biochemical process that regulates gene expression (i.e., turning genes on and off). It also governs intracellular detoxification, regulates protein function and RNA production, and supports the immune system.
MTHFR may also elevate homocysteine but this is not the main reason to get tested. The sooner you know if you have a mutation the sooner you can take step to address it and prevent possible complications.
No. Methylation imbalances often start with no symptoms until much later as your body starts to break down. When that happens, depending on the system that is breaking down you may experience a variety of different MTHFR mutation symptoms.
The MTHFR C677T gene produces a functioning MTHFR enzyme that converts methyfolate to 5-MTHF and helps regulate homocysteine levels.
Supplementing with 5-MTHF is essentially bypassing this enzyme. High dosing of 5-MTHF (1mg or more) however can cause high nitric oxide levels leading to anxiety and panic attacks, especially those with low protein diets, low electrolytes, and SNPs in COMT, SOD, and glutathione.
If the MTHFR C677T gene has heterozygous or homozygous variants, the enzyme is slowed down, and folate does not effectively convert to the active 5-MTHF (methylfolate).
Therefore, MTHFR can affect mood disorders. BH4 also play a role in the detoxification of ammonia (by-product of protein metabolism).
As you will see in the table below, a heterozygous MTHFR does not always mean folate and B12 supplementation are needed. This is why it is important to look at all the other genes/enzymes in the methylation cycle to determine the exact nutrient needs for healthy homocysteine.
MTHFR is an enzyme critical for human body functioning. Enzymes are used as in-betweeners for two things, for example, the enzymes in your clothes-washing detergent break down dirt and grease, allowing them to be dissolved in water and rinsed away.
Variations in the MTHFR gene (polymorphism, defect, mutation) can be inherited from your parents and in fact, are very common. So far there are about 30 different mutations recorded, with C677T and A1298C two of the most well-studied and tested mutations 2.
We never assume the MTHFR gene mutation will cause problems – everyone’s different. But, we know that some variants have greater potential for problems than others.
The MTHFR mutations can impact homocysteine levels in the blood. Homocysteine is an amino acid that is broken down by L-methylfolate – the active form of folate. Less L-methylfolate means higher homocysteine levels.
L-methylfolate is a key nutrient in methylation. If you’re not methylating effectively, several other enzymes that break down important body products like histamine do not work effectively, resulting in build-up. MTHFR and histamine are closely linked, and a major cause of vaginal symptoms
