Association of NCOA2 gene polymorphisms with obesity and dyslipidemia in the Chinese Han population.

Nuclear receptor coactivator 2 (NCOA2) gene plays an important role in adipogenesis and lipid metabolism. NCOA2 gene null mice exhibited less fat accumulation and lower serum lipid levels, and were protected against obesity. Few studies are known to have analyzed the association of NCOA2 gene single nucleotide polymorphisms with obesity and serum lipid profile. Our study aimed to evaluate the association of NCOA2 gene polymorphisms with the risk of obesity and dyslipidemia in the Chinese Han population. Two NCOA2 gene polymorphisms (rs41391448 and rs10504473) were selected and genotyped in a Chinese Han cohort with 529 participants. The effect of different genotypes on BMI and serum lipid levels (TG, TC, LDL-C and HDL-C) was performed by the analysis of covariance. Association of NCOA2 polymorphisms with obesity and dyslipidemia was assessed by odds ratios (OR) and 95% confidence intervals (CI) under the unconditional logistic regression analysis. Significant association was observed between rs10504473 polymorphism and obesity under the recessive model (OR = 1.88, 95% CI 1.02-3.45, P = 0.047; adjusted OR = 1.87, 95% CI 1.02-3.44, P = 0.048). However, no association remained significant after Bonferroni correction. Our study suggests a possible association between NCOA2 rs10504473 polymorphism and obesity, and this SNP may influence the susceptibility of obesity in the Chinese Han population.
