Intended purpose

The assay attomol® Factor V Leiden Realtime LT is used for the supportive diagnosis of thrombophilia. This test can be used to determine the transition 1691G>A in the human factor V gene (Leiden mutation, rs6025). It is a manual, qualitative real-time PCR assay based on a LoopTag probe, which is evaluated by a melting curve analysis. The sample material has to be genomic DNA prepared from EDTA or citrate blood.

Field of application

The factor V Leiden mutation, which has a prevalence of approximately 5 % in the European population, is one of the most important hereditary risk factors for thrombosis. In the blood coagulation cascade factor V forms a complex (prothrombin activator) together with the activated factor X, phospho-lipids, and calcium ions. This complex converts prothrombin (factor II) into thrombin, which causes a fibrin polymerization. The inactivation of factor V occurs through the activated protein C (APC). The substitution of guanine (G) for adenine (A) at position 1691 of the factor V gene results in an amino exchange in the binding site for APC. This leads to the fact that factor V can only be insufficiently cleaved and thus inactivated [Bertina et al., 1997, Nature 369: 64-67]. The resulting accumulation of factor V in the blood leads to an increased coagulation tendency, which results in a higher risk of thrombosis in the affected patients. Homozygous mutations in the factor V gene lead to a significantly higher risk than heterozygous defects [Zöller et al., 1999, Haematologica 84: 59-70].
