Investigation of the Frequency of Thrombophilic Gene Mutations in Patients with Venous Thromboembolism in Eastern Turkey
Objectives: Polymorphisms in the thrombophilia genes such as Factor V Leiden (FVL), Prothrombin G20210A and methylenetetrahydrofolate reductase (MTHFR) cause genetic predisposition to thrombophilia. The regional incidence of these polymorphisms varies. The aim of our study is to evaluate the regiona...

| Summary: | Objectives: Polymorphisms in the thrombophilia genes such as Factor V Leiden (FVL), Prothrombin G20210A and methylenetetrahydrofolate reductase (MTHFR) cause genetic predisposition to thrombophilia. The regional incidence of these polymorphisms varies. The aim of our study is to evaluate the regional frequency of the most common single nucleotide polymorphisms of these thrombophilia genes.
Methods: In this retrospective study, patients diagnosed with VTE in our center were included in the study. The presence of FVL, Prothrombin G20210A, MTHFR C677T, MTHFR A1298C, plasminogen activator inhibitor (PAI)-1, β-Fibrinogen, Factor XIIIA (V34L) and Glycoprotein IIIA (L33P) were investigated in blood samples obtained from the patients, and the association of genotype disorders was also evaluated.
Results: Eight genotypes were analyzed in 2000 patients whose thrombophilia panel was studied in our clinic. The frequency of heterozygosity for the Factor II G20210A polymorphisms was 4,6%, the homozygosity for the Factor V Leiden polymorphism was 0,4%, for MTHFR C677T 7,6% , for MTHFR A1298C 48,1% and 15,7% , for PAI-1 38,8% and 13% , for β-Fibrinogen 30,3% and 4%, for Factor XIIIA (V34L) 23,3% and 2,4% and for Glycoprotein IIIA (L33P) 17,7% and 1,5% respectively.
Conclusions: Factor V Leiden and Factor II (Prothrombin) G20210A mutations were found at a higher rate in our region compared to other regions in the west. |
