Each child has a 100% chance of having at least one copy of Factor 5 Leiden. Factor V Leiden is the name of a specific gene mutation that results in thrombophilia, which is an increased tendency to form abnormal blood clots that can block blood vessels. The molecular study of genetic thrombophilias was negative for prothrombin 20210G>A mutation but revealed heterozygosity for factor V Leiden (mutation 1691G>A). One of the anticoagulant mechanisms by protein C is degradation of factor V. In factor V Leiden, the altered factor V significantly reduces binding to activated protein C, so there's more factor V available to facilitate thrombin generation, and therefore a higher propensity for thrombosis. Activated factor X is another factor upstream from factor V in the coagulation cascade.
