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. FVL is caused by a genetic mutation to the Factor V (or “factor 5”) gene. This gene helps our body make the coagulation factor V protein, which is one of the many proteins in our coagulation system that help our blood clot after an injury.

Coagulation factors are proteins circulating in the blood that are essential for proper blood clot formation. Coagulation factor tests measure the function of or sometimes the amount of these proteins in the blood. Blood clotting is a complex process that involves numerous coagulation factors, which are produced by the liver and blood vessels.

PT and APTT are prolonged in factor V deficiency. Thrombin time is normal. Treatment: These patients are treated Factor V (also known as labile factor) is highly susceptible to proteolytic inactivation, with the potential for spuriously decreased assay results.

Apr 16, 2019 FVL results from a mutation (change) of the gene that makes one of the proteins of our coagulation system, called factor V (or “factor 5”).

Coagulation factor v

Factor V is a major cofactor that converts prothrombin to thrombin and plays an important role in the coagulation pathway by regulating factor Ⅷ activity.

In contrast to most other coagulation  Mar 14, 2017 Because the venous thromboembolisms (VTEs) due to the coagulation factor V R506Q (FV Leiden) mutation is often seen in Caucasians, the  FVL is a genetic mutation in the clotting factors of the blood. In most people the body can counteract it however in others it can be very dangerous.
