Abstract:

Objective To determine the prevalence of F Ⅹ Ⅲ A Val34Leu (100G/T) and F Ⅹ Ⅲ B His95Arg (8259A/G) polymorphisms in Chinese Han population and to investigate whether they were associated with pulmonary thromboembolism pulmonary thromboembolism(PTE).Methods The subjects consisted of 114 patients with PTE and 114 healthy controls matched in age, sex and race. All patients were diagnosed by lung ventilation/perfusion scan and/or multi-slice CT pulmonary angiography. Genome DNA was extracted from whole blood using phenol-chloroform. Genotypes and allele frequencies of F Ⅹ Ⅲ A Val34Leu (100G/T) and F Ⅹ Ⅲ B His95Arg (8259A/G) polymorphisms were examined by PCR-RFLP. Results Regarding F Ⅹ Ⅲ A Val34Leu and F Ⅹ Ⅲ B His95Arg polymorphisms,the allele frequencies G and T of F Ⅹ Ⅲ A Val34Leu in the controls were 0.996, 0.004, while A and G of F Ⅹ Ⅲ B His95Arg were 0.956, 0.044 respectively, which were in good agreement with Hardy-Weinberg equilibrium. The genotype TT (Leu/Leu) of F Ⅹ Ⅲ A Val34Leu polymorphisms was not detected. The distributions of genotype GG (Val/Val), GT (Val/Leu) were similar between the patients and controls. The genotype GG (Arg/Arg) of F Ⅹ Ⅲ B His95Arg polymorphisms was not detected. The genotype AG (His/Arg) was a protective factor for PTE patients (OR=0.281, 95%CI: 0.075-1.050( P=0.046). Conclusion The allele T (Leu) of F Ⅹ Ⅲ A Val34Leu polymorphism is rare and may be not association with PTE in Chinese Han population. The genotype AG (His/Arg) of F Ⅹ Ⅲ B His95Arg may be a protective factor for PTE patients.
