How common is factor 5 leiden
WebAbstract Background and purpose: Resistance to activated protein C is a common inherited risk factor for venous thrombosis, which is due to a mutation in coagulation factor V (factor V Leiden mutation). It is present in approximately 20% of unselected consecutive patients with deep vein thrombosis. WebWomen who have heterozygous Factor V Leiden have an 8- to 52-fold increase depending on coexisting risk factors such as obesity or advanced age. Homozygous carriers have much higher risks with some studies claiming as high as 100-fold.

Factor V Leiden (rs6025 or F5 p.R506Q ) is a variant (mutated form) of human factor V (one of several substances that helps blood clot), which causes an increase in blood clotting (hypercoagulability). Due to this mutation, protein C, an anticoagulant protein that normally inhibits the pro-clotting activity of factor V, is not able to bind normally to factor V, leading to a hypercoagulable state, i.e., an increased tendency for the patient to form abnormal and potentia… WebFactor V Leiden is a genetic disease characterized by a mutant factor V which resists inactivation by Activated Protein C (APC).
