Association of endothelial lipase gene？384A/C with coronary artery disease in Han Chinese people

Objectives The endothelial lipase gene ( LIPG ) is one of the important genes in the metabolism of high-density lipoprotein cholesterol (HDL-C) and may be involved in the pathogenesis of coronary artery disease (CAD). Materials and methods To investigate the relationship between the common single nucleotide polymorphisms (SNPs) 584C/T (rs2000813) and ？384A/C (rs3813082) in the LIPG gene and CAD, allele and genotype frequencies of the two SNPs were analysed in 287 Chinese patients with CAD and 367 controls by the high-resolution melting curve (HRM) method. Results For 584C/T, no significant difference in polymorphic distribution was observed between patients and controls. However, the frequencies of allele C (20.2% vs 15%, p=0.013, OR=1.437, 95% CI 1.078 to 1.915) at ？384A/C were significantly increased in patients compared with controls. Haplotype analysis also showed that haplotype CT (12.37% vs 8.72%, p=0.035, OR=1.478, 95% CI 1.034 to 2.112) was significantly higher in patients compared with controls. Conclusions These results suggested that the SNP ？384A/C in the LIPG gene may be associated with risk for CAD and the LIPG gene may play a role in CAD in the Han Chinese
