Abstract:
This study was aimed to explore the change of single nucleotide polymorphism (SNP) of thrombin-activatable fibrinolysis inhibitor (TAFI) and its correlation of 2 sites (505a/g, 1040c/t) in its gene-coding region with venous thromboembolism (VTE). The genotype distribution of TAFI in 80 patients with VTE and 80 normal controls was detected by allele-specific PCR. The results showed that the distribution of each genotype of 505a/g polymorphism was not significantly different between the VTE and control groups (P > 0.05). However, t allele frequency of 1040c/t in VTE group decreased significantly as compared with the control group (40% vs 53.75%, P < 0.05), mainly due to the decrease of the proportion of tt homozygous in VTE group. It is concluded that obvious relationship is found between the polymorphism of 1040c/t in TAFI gene and VTE patients. t allele genotype may paly a protective role in VTE. The polymorphism of TAFI 505a/g may be not associated with VTE.
