Factor V Leiden Analysis Factor V Leiden (F5) R506Q mutation is the most common cause of inherited thrombophilia and accounts for over 90 percent of activated protein C (APC) resistance. Individuals heterozygous for this mutation have an increased risk for venous thrombosis (approximately five- to tenfold) Factor V Leiden (FVL) results from a point mutation in the F5 gene, which encodes the factor V protein in the coagulation cascade. FVL renders factor V (both the activated and inactive forms) insensitive to the actions of activated protein C (aPC), a natural anticoagulant. As a result, individuals who carry the FVL variant are at increased risk. The risk is increased 20- to 40-fold in women with homozygous Factor V Leiden. 66,73,74 In one study, the risk for pregnancy-associated VTE was increased 9-fold in Factor V Leiden heterozygotes.

Objective: To assess the risks and benefits of oral anticoagulant treatment extended beyond 3 months after a first episode of deep vein thrombosis in patients who carry factor V Leiden mutation. Such patients have over twice the risk of recurrence after the recommended treatment period, but more information is required before widespread genetic screening can be recommended If you have thrombophilia, it means your blood can form clots too easily. Blood clots can be very serious and need to be treated quickly. Thrombophilia increases your risk of: deep vein thrombosis (DVT), a blood clot in a vein, usually the leg. pulmonary embolism (PE), a blocked blood vessel in your lungs. Information Factor V Leiden is a genetic disorder. An abnormality in the affected individual's DNA results in the production of an abnormal form of Factor V. The amount of abnormal Factor V, and the severity of disease, depends on the presence of one or two copies of the mutated gene. Those with one copy are 10 times as likely to have a significant. Objective: To determine whether methylene tetrahydrofolate reductase (MTHFR) C677T mutation, factor II G20210A mutation and factor V Leiden are risk factors for retinal vein occlusion (RVO) in patients under fifty years of age.

Some clots do no damage and disappear on their own. Others can be life-threatening

Factor V Leiden is the most common inherited blood clotting disorder. It increases the risk for deep vein thrombosis (blood clots that appear deep in the body, usually in the thigh or lower leg) and pulmonary embolism (when a blood clot travels through the blood system to the lungs) THE G1691A mutation in the factor V (FV) gene (FV Leiden) is currently the most frequent genetic cause of thrombophilia. 1,2 Factor V Leiden is common among whites, with a prevalence of up to 15% in healthy individuals and 17% to 56% (depending on patient selection) in thrombosis cohorts. 3-5 In contrast to less common thrombotic risk factors, such as deficiency in antithrombin, protein C, or. The factor V Leiden variant (HGVS nomenclature NM_000130.4 c.1691G>A p.R534Q; legacy nomenclature R506Q, p.Arg506Gln, 1691G>A) in the factor V gene (F5) is present in approximately 3% of the general population, and in about 20-50% of patients with a history of unexplained recurrent venous thrombosis

Coexistent heterozygous factor V Leiden and homozygous prothrombin G20210A gene mutations is a rare and potentially life-threatening occurrence. This inherited thrombophilia often presents as non-specific venous thromboemboli and can mimic a variety of emergent medical conditions. The pathophysiology of the disease has been well documented; however, long-term treatment efficacy remains poorly. Most people with Factor V Leiden do not develop blood clots and do not need treatment. If blood clots become an issue, blood-thinning medicines (like Enoxaparin) can be used. This will halt growth of the clot and reduce the risk of future clots. Prevention. Since Factor V Leiden is an inherited condition, there is no way to prevent it

Factor V Leiden: A genetic disorder of blood coagulation (clotting) that carries an increased risk of venous thromboembolism -- the formation of clots in veins that may break loose and travel through the bloodstream to the lungs or brain. On the molecular level, factor V Leiden is characterized by a G to A substitution at nucleotide 1691 in the gene for factor V that causes a single amino acid.

The mutation is actually a common polymorphism in the Factor V gene that replaces a critical arginine with a glutamine at position 506 of the protein (FV R506Q). This removes a cleavage site for activated protein C. Approximately 5% of Caucasians is heterozygous for the R506Q polymorphism. Heterozygous FV R506Q carriers have a 4-fold risk. The factor V Leiden mutation is involved in some cases of a condition known as Budd-Chiari syndrome. This condition is characterized by a blockage of blood flow from the liver, which can be caused by a blood clot. People with thrombophilia, including that caused by the factor V Leiden mutation, have an increased risk of developing Budd-Chiari.
