[Study on the association between polymorphisms in angiotensinogen gene and deep venous thrombosis].
OBJECTIVE
To investigate the association of polymorphism of angiotensinogen (AGT) -6G/A, -20A/C and T174M with the development of deep venous thrombosis.


METHODS
One hundred and three patients with deep venous thrombosis (DVT group) and 250 healthy subjects (control group) were recruited in the study. The polymorphisms of angiotensinogen -6G/A, -20A/C and T174M were detected by PCR-RFLP.


RESULTS
The prevalence of GA genotype of -6G/A in the DVT group was significantly higher than that in the control group(P< 0.05) and the prevalence of -20A/-6A/174T haplotype in the DVT group was lower than that in the control group(P< 0.05). There were no significant differences in the prevalence of -20A/C and T174M polymorphism.


CONCLUSIONS
The GA genotypes of -6G/A may increase the development of DVT and the -20A/-6G/174T haplotype may be a risk factor of DVT. However, the -20A/-6A/174T haplotype may be a protective factor of DVT.
