    Blood clotting factor V is a protein that plays an important role in both procoagulant and anticoagulant pathways of hemostasis. Genetic and acquired disorders can lead to thrombotic and hemorrhagic events by affecting the activity or expression of FV molecule. FVL mutation is seen in 20% of patients with venous thrombosis and this proportion rises to 50% in selected thrombophilia patients. FVL mutation is a risk factor with the same effects as coagulation inhibitor deficiencies. The risk of thrombosis increases 5-fold with heterozygote mutation while a 50-100 fold increase in thrombosis is seen with homozyogote mutation.In this study, real time PCR technique is used to detect FVL mutation. F5 gene is amplified by polimerase chain reaction (PCR) using appropriate primers for promotor region. -426 G/A change is detected by imaging band profiles obtained by RFLP (Restriction Fragment Length Polimorfizm) in 3% agaroz gel.The objective of this study is to find the effect of -426 G/A gene change present in the promotor region of F5 gene on thrombosis. The effect of -426 G/A gene change on thrombosis in individuals who are homozygote for FVL mutation and have or have not had a thrombotic episode is investigated. No significant difference with respect to genotype and allele distribution of -426 G/A polimorfizm was detected between homozygote carriers of the FVL mutation who did or did not suffer a thrombotic episode
