Factor V (pronounced factor five) is a protein of the coagulation system, rarely referred to as proaccelerin or labile factor.In contrast to most other coagulation factors, it is not enzymatically active but functions as a cofactor.Deficiency leads to predisposition for hemorrhage, while some mutations (most notably factor V Leiden) predispose for thrombosis
Factor V Leiden (rs6025) 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 which 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.

This test detects the factor V R506Q (Leiden) mutation and will help identify those individuals who are at increased risk of thrombosis; however, increased risk of thrombosis can be caused by a variety of genetic and nongenetic factors not screened for by this assay.
The first genetic variants tested were usually restriction fragment. the association between deep venous thrombosis and factor V Leiden, a common polymorphism in the gene encoding clotting factor V.
Cern What Does It Do If General Heuer and Director Bertolucci’s comments really do reflect the ultimate aspirations of CERN, and we have no reason to believe they do not, then it is clear that their intention is to rip open the veil separating this world from other worlds or dimensions.

DALLAS, March 31 — Men with high blood levels of an amino acid called homocysteine and a hereditary blood clotting disorder called Factor V Leiden have a far greater relative risk of forming.
Factor V Leiden is the most common inherited form of thrombophilia. The risk of developing a clot in a blood vessel depends on whether a person inherits one or two copies of the factor V Leiden mutation.
The factor V Leiden mutation causes activated protein C (APC) resistance and increases the risk for venous thrombosis and pulmonary embolism. Heterozygotes (with one copy of the mutation) have a sevenfold increased risk, and homozygotes (with two copies) have a 50% to 80% increased risk.

A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or.
