Genetic Mutations in Turkish Population With Pulmonary Embolism and Deep Venous Thrombosis

Abstract

Venous thromboembolism (VTE) is a universal health hazard. Inherited and acquired risk factors increase the risk of VTE. We evaluated the relationship between factor V (G1691A, A1090G, and A1299G), prothrombin (PT G20210A), methylenetetrahydrofolate reductase (MTHFR C677T) mutations, plasminogen activator inhibitor 1 (PAI-1 -675) polymorphism, and VTE in Turkish population. In all, 80 patients with VTE and 104 controls were included. Heterozygous factor V Leiden (FVL) mutation was significantly higher among patients ( P = .04) with allele frequency of 6.3% ( P = .01). Heterozygous PT G20210A mutation was also significantly higher among patients ( P = .001) with allele frequency of 6.9% ( P = .003). MTHFR 677TT genotype was significantly higher in patients ( P = .009) with allele frequency of 23.8% ( P = .005). No significant difference was found in FV A1090G and FV A1299G mutation rate as well as PAI-1 genotypes and their allele frequencies ( P > .05). Thus, frequencies of FV G1691A, PT G20210A, and MTHFR C677T mutations are higher in patients with VTE. FV A1090G, FV A1299G mutations, and PAI-1 gene polymorphisms may not be a risk factor for VTE in Turkish population.
