What is prothrombin G20210A mutation?
Prothrombin gene mutation (or Factor II mutation or Prothrombin G20210A) is an inherited condition that increases your predisposition to develop abnormal blood clots in the veins (deep vein thrombosis or DVT) and lungs (pulmonary embolism or PE).
What is prothrombin gene mutation heterozygous?
Having the Prothrombin Gene Mutation increases your risk of having a blood clot. If you have one copy of the Prothrombin Gene Mutation (also called being a heterozygote for this gene), you are at around 3 times more at risk of developing a blood clot compared to someone your age who does not have this gene change.
Is prothrombin gene mutation genetic?
A Genetic Clotting Condition or Thrombophilia Prothrombin 20210 Mutation, also called Factor II Mutation is a genetic condition that causes an increase in the likelihood of your blood forming dangerous blood clots. All individuals make the prothrombin (also called factor two) protein that helps blood clot.

How serious is prothrombin gene mutation?
Having the prothrombin mutation increases the risk of developing a DVT (a blood clot in the deep veins, typically the legs) and/or PE (blood clot that travels to the lungs). DVTs are dangerous because they can damage the veins, leading to pain and swelling, and sometimes to disability.
What do you do if you have a prothrombin mutation?
No treatment can prevent the prothrombin gene mutation or make it go away. The goal of treatment is to prevent blood clots (see next question and page 7). If you have had a blood clot, you may be treated with medications called anticoagulants. Anticoagulants are used to help to prevent blood clots.
Can you have a baby with prothrombin gene mutation?
The second most common genetic type is prothrombin thrombophilia, which mainly affects people of European ancestry. It involves a mutation in the F2 gene. Genetic types of thrombophilia may raise the risk of multiple miscarriages, but most women with these genetic mutations have normal pregnancies.
How common is the MTHFR gene mutation?
MTHFR gene polymorphisms are common worldwide, with an estimated 25 percent of Hispanics and 10 to 15 percent of North American whites having the 677C>T polymorphism in both copies of the gene. Most people with MTHFR gene polymorphisms do not have neural tube defects, and their children are also typically unaffected.
What causes MTHFR gene mutation?
People inherit one copy of the MTHFR gene from each of their parents, which means that everyone has two MTHFR genes. Mutations can occur in one or both of these genes. Having a parent or close relative with an MTHFR gene mutation can increase a person’s risk of inheriting the same variant themselves.
Whats worse Factor 2 or Factor 5?
The Factor V variant known as Factor V Leiden (or rs6025) is associated with an approximately 300% increased risk in heterozygotes and an up to 8000% increased risk in homozygotes. The Factor II rs1799963 polymorphism (or G20210A) may also independently increase the risk by approximately 200%.
Does prothrombin gene mutation cause miscarriage?
Apart from blood clots, prothrombin mutations are associated with an increased risk of complications during pregnancy. These complications include: pregnancy loss (miscarriage or stillbirth) preeclampsia (increased blood pressure and protein in the urine during pregnancy)
What does A1298C mutation mean?
The A1298C mutation, like the C677T mutation, results in a decrease in MTHFR activity that is more pronounced in the homozygous (CC) than in the heterozygous (AC) or normal (AA) states, and does not result in a thermolabile protein.
What are the signs of MTHFR?
MTHFR Mutation Symptoms:
- Depression.
- Bipolar disorder.
- Anxiety.
- Schizophrenia.
- Acute leukemia.
- Colon cancer.
- Cardiovascular and thromboembolic disorders.
- Chronic pain and fatigue.
Is factor V Leiden life threatening?
Factor V Leiden can cause blood clots in the legs (deep vein thrombosis) and lungs (pulmonary embolism). These blood clots can be life-threatening.
How is MTHFR A1298C treated?
MTHFR mutations do not require medical treatment. That said, making dietary and lifestyle changes can often help offset any resulting nutritional deficiencies. For example, people with high homocysteine levels due to folate or vitamin B12 deficiencies can take folic acid or vitamin B12, respectively.
What does it mean to be positive for two copies of the A1298C mutation?
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.
