Abstract
OBJECTIVE: To assess the association between coronary heart disease (CHD) and vitamin D receptor (VDR) gene polymorphisms in Han Chinese adults. METHODS: A total of 215 CHD patients and 67 controls were recruited. In both groups, the VDR gene single nucleotide polymorphisms (SNP) of Tru9I (rs757343), ApaI (rs7975232), TaqI (rs731236) and FokI (rs2228570) were detected, and the frequencies of VDR genotypes were compared between patients and controls. The relationship between VDR FokI genotype and risk for CHD was assessed by logistic regression analysis after adjusting for age and sex. In addition, the clinical parameters and biochemical characteristics of CHD subgroups were compared according to the VDR FokI polymorphism. RESULTS: The frequencies of FokI genotypes in CHD patients were 23.7% for AA, 47.9% for AG, and 28.4% for GG. The frequency of FokI-GG genotype significantly decreased in CHD patients as compared to control group (P = 0.039). No significant differences were observed in other VDR SNPs (rs7975232, rs731236 and rs757343) (P > 0.05) between groups. FokI-A allele carriers had a 2.61-fold increase in the odds (95% CI: 1.116-6.102, P = 0.027) as compare to CHD subjects with FokI mutation. In CHD subgroup, patients with GG genotype had a significantly higher concentration of high-density lipoprotein cholesterol than those with AG genotype or A* genotype (P = 0.001, respectively). CONCLUSION: VDR FokI polymorphisms appear to be associated with CHD. GG genotype predicts a higher HDL-cholesterol in CHD adults.
