RESUMO
We investigated the relationship between the polymorphism of SOCS-3 and dyslipidemia of people from Uygur in Xinjiang, China. This cross-sectional study included 1379 participants in a Hetian Xinjiang Uygur population who were 30-70 years of age and were not from interracial marriages of 3 generations; all subjects were genotyped (909 dyslipidemia subjects, 470 healthy subjects). Allele (P = 0.002) and genotype (P = 0.003) frequencies of the distribution of rs12953258 was significantly different between dyslipidemia and control groups. Between the total cholesterol abnormal and control groups, high-density lipoprotein cholesterol abnormal and control groups, triglycerides abnormal and control groups, the frequencies of genotype in rs12953258 were significantly different (P = 0.007, 0.012, 0.0004, respectively). Based on the logistic regression analysis, genotype CA and AA of rs12953258 were independent and risk factors for dyslipidemia in Uygur (CC vs CA; odds ratio = 1.48, 95% confidence interval = 1.11-1.98, P = 0.008), (CC vs AA; odds ratio = 2.48, 95% confidence interval1.07-5.79, P = 0.035). Genotype AA of rs12953258 merged with subjects whose waist-to-hip ratio was abnormal, indicating the presence of dyslipidemia. The frequency of haplotype 4(H4) A-G-C in the dyslipidemia group was higher than in the control group (8.44 vs 5.37%, P = 0.003). rs12953258 site of the SOCS-3 gene showed a close relationship with dyslipidemia in Uygur. Combining genotype AA with subjects whose waist-to-hip ratios were abnormal will increase prevalence of dyslipidemia obviously.
