What Is Factor II mutation?

What Is Factor II 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).

How many people have Factor 2 mutations?

The mutation is uncommon in African Americans (approximately 0.5%) and is rare in Asians, Africans, and Native Americans. The homozygous form is considered uncommon, with an expected occurrence of approximately 1 in 10 000 individuals. The prothrombin 20210 mutation is equally as common in men and in women.

What is factor 2 blood disorder?

Factor II deficiency is a very rare blood clotting disorder. It results in excessive or prolonged bleeding after an injury or surgery. Factor II, also known as prothrombin, is a protein made in your liver. It plays an essential role in blood clot formation.

Can I donate blood with prothrombin gene mutation?

People with factor V Leiden may donate blood, platelets or plasma safely, as long as they are not on an anticoagulant such as warfarin. Only a very few medicines prevent people from donating blood.

Is Factor 2 a bleeding disorder?

Clotting factor II, or prothrombin, is a vitamin K–dependent proenzyme that functions in the blood coagulation cascade. Factor II deficiency is a rare, inherited or acquired bleeding disorder with an estimated incidence of one case per 2 million population.

How is factor 2 diagnosed?

Testing. Diagnosis is made with a prothrombin time (PT) test and an activated partial thromboplastin time (aPTT) test. Levels of prothrombin deficiency can range from 2% to 50% of normal. Patients with levels near or at 50% of normal have little to no bleeding problems.

Is Factor 2 mutation rare?

A change in the prothrombin gene is present in 2-4% (or 1 in 50 to 1 in 25) of Caucasians, and is more common in individuals of European ancestry. In the United States, approximately 0.4% (about 1 in 250) of African Americans also have the mutation. Prothrombin G20210A mutation is rare in other groups.

How is factor 2 treated?

Treatment of factor II deficiency is aimed at restoring circulating factor II to levels sufficient for hemostasis. Levels greater than 30% of normal are usually adequate. Treatment measures include fresh frozen plasma (FFP), prothrombin complex concentrates (PCCs), and vitamin K.

Is prothrombin gene mutation curable?

Can the prothrombin gene mutation be treated? 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.

What is the gene mutation that causes blood clots?

Factor V Leiden (FAK-tur five LIDE-n) is a mutation of one of the clotting factors in the blood. This mutation can increase your chance of developing abnormal blood clots, most commonly in your legs or lungs. Most people with factor V Leiden never develop abnormal clots.

What does a protime test for?

A prothrombin time (PT) is a test used to help detect and diagnose a bleeding disorder or excessive clotting disorder; the international normalized ratio (INR) is calculated from a PT result and is used to monitor how well the blood-thinning medication (anticoagulant) warfarin (Coumadin®) is working to prevent blood …

How is prothrombin gene mutation treated?

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.
