[Association of the polymorphism of synaptobrevins/vesicle-associated membrane proteins 8 gene with coronary heart disease in Chinese Han population].

OBJECTIVE
To investigate the association of synaptobrevins/vesicle-associated membrane proteins 8 (VAMP8) gene rs1010 polymorphism with coronary heart disease (CHD) in Chinese Han population.


METHODS
The allele and genotype frequencies of the VAMP8 gene rs1010 locus in 185 CHD patients and 149 controls were analyzed by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing.


RESULTS
There was polymorphism of the VAMP8 gene rs1010 locus in the studied population. The distribution of VAMP8 genotypes was in Hardy-Weinberg equilibrium. The frequency of the A allele in the CHD group was significantly higher than that in control (67.3% vs 53.0%, P< 0.05). Multiple logistic regression analysis showed that genotypes AA and AG were independent risk factors of coronary heart disease. The odds ratio (OR) of (AA+AG) genotype versus GG genotype was 1.969,95% CI: 1.032-3.755.


CONCLUSION
The VAMP8 rs1010 polymorphism was associated with CHD risk in Chinese Han population, the A allele might serve as a genetic risk factor of coronary heart disease.
