RESUMEN
Objective To explore the relation of newly genome-wide association study (GWAS) identified lipid-associated genes by euramerican white and coronary heart disease ( CHD ) susceptibility in Chinese Han population. Methods One thousand patients with CHD were enrolled according to WHO criteria. 1000 age-and sex-matched controls were included. Single-nucleotide polymorphisms (SNPs) were detected by Taqman technique. Results Two novel SNPs (rs599839 in SORT1 region and rs16996148 in NCAN region) were significantly associated with CHD risk in Chinese Han population. Compared to AA genotype of rs599839, subjects with AG genotype of rs599839 (OR=0.64, 95%CI=0.48~0.85, P=0.002 and OR=0.67, 95%CI=0.52~0.91, P=0.008, respectively). Compared to GG genotype of rs16996148, subjects with GT genotype were associated with significantly decreased risk of CHD(OR=0.67, 95%CI=0.52~0.91, P=0.008). Two another SNPs (rs12695382 in B4GALT4 region and rs2254287 in B3GALT4 region) were not significantly associated with CHD in Chinese Han population. Conclusions Two novel SNPs (rs599839 and rs16996148) at newly identified lipid-associated loci were significantly associated with CHD susceptibility in Chinese Han population.
