    Abstract:
    AIM: Our aim was to investigate the association between single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor (VEGF) and coronary heart disease (CHD) susceptibility in Chinese Han population. METHODS: 144 CHD patients and 150 healthy individuals were enrolled in the study. Three SNPs (936C/T, -460T/C and -634G/C) of VEGF were chose and then were genotyped with Sequenom time-of-flight mass spectrometry (TOFMS). Odds ratio (OR) with 95% confidence interval (CI) were used to evaluate the association of genotypes and haplotypes and CHD susceptibility. RESULTS: The frequencies of -460T/C CC genotype (13.6%) was found higher in the case group than that of control group (6.7%), which indicated that CC genotype was a risk factor for CHD (OR=2.50, 95% CI=1.10-5.68). Correspondently, the C allele appeared to increase the risk of CHD (OR=1.54, 95% CI=1.07-2.22). For -634G/C polymorphism, the risk of the CC genotype carrier for CHD increased 2.24 fold compared to the wild genotype. Moreover, -634G/CC allele was significantly associated with CHD susceptibility (OR=1.65, 95% CI=1.15-2.36). In addition, +936C/T CT genotype and C allele appeared to be a genetic-susceptibility factors for CHD (OR=2.43, 95% CI=1.44-4.10; OR=1.95, 95% CI=1.26-3.02). The haplotype analysis showed that T-C-T, C-C-C and C-G-C haplotypes all could increase the risk for CHD (OR: 2.43, 2.77 and 2.33). CONCLUSION: we concluded VEGF polymorphisms were associated with CHD susceptibility. Moreover, the haplotypes of T-C-T, C-C-C and C-G-C all could increase the risk for CHD.
