Genetic screening of variants associated with thrombosis. Common variants associated with thrombosis are Factor V Leiden, Prothrombin 20210 G>A, Methylenetetrahydrofolate reductase (MTHFR) C677T variants. They are usually screened by PCR and RFLP or by sequencing.
Inherited thrombophilia is a genetic predisposition to developing thromboembolic complications. These prothrombotic risk factors include defects of coagulation factor inhibitors, increased levels or function of coagulation factors, fibrinolytic system, platelet function, and hyperhomocysteinemia. Common variants associated with thrombosis are Factor V Leiden, Prothrombin 20210 G>A, Methylenetetrahydrofolate reductase (MTHFR) C677T variants. They are usually screened by PCR and restriction fragment length polymorphism (RFLP) or by sequencing.
