摘要目的 研究神经前体细胞表达发育调控样基因rs4149601多态性与新疆哈萨克族人群中心性肥胖的相关性.方法 采取以人群为基础的横断面病例-对照研究方法,采用TaqMan聚合酶链反应对新疆哈萨克族856名自然人群(男性364名、女性492名;其中肥胖478例、对照378名)的rs4149601多态性进行分型,分析其与新疆哈萨克族人群肥胖的相关性.结果 共有853名的基因型分型成功,在总体女性新疆哈萨克族自然人群中,rs414960l多态性的基因型、等位基因在肥胖组及对照组分布差异有统计学意义(P＜0.05).在校正了年龄、吸烟、饮洒和性别等影响因素后,Logistics回归分析显示GG基因型仍与新疆哈萨克族人群中心性肥胖相关(OR=1.479,95%CI:1.103～1.983,P=0.009);协方差分析结果提示携带GG基因型者的腰围高于AA携带者+AG携带者(P=0.028).结论 神经前体细胞表达发育调控样基因的rs4149601多态性与新疆哈萨克族人群中心性肥胖相关,GG基因型可能是哈萨克族人群中心性肥胖的易感因素.

abstractsObjective To investigate the association of the rs4149601 polymorphisms of neural precursor cell expressed developmentally downregulated 4-like gene (NEDD4L)and obesity in Xinjiang Kazakh population. Methods The rs4149601 polymorphism of the NEDD4L gene was genotyped in a Xinjiang Kazakh general population including 856 subjects (aged 30 to 60 years, 478 obese and 378 control individuals). Results The polymorphism was successfully genotyped in 853 Xinjiang Kazakh subjects. The distribution of the additive model and dominant model (AG+ AA vs. GG) of the rs4149601 polymorphism differed significantly between the case and control in both total and females (all P＜0. 05). After adjusting for confounding factors, logistic regression analysis showed that the rs4149601 polymorphism (in dominant model) was significantly associated with obesity (OR= 1. 479, 95% CI: 1. 103-1. 983, P = 0. 009) in Kazakh. Covariate variance analysis showed that compared with subjects with AA + AG genotypes, the waist circumference was significantly higher in subjects with GG genotype after adjusting for age, smoking and drinking (P=0. 028). Conclusion Tbe genetic variations of the NEDD4L gene may be associated with obesity in Xinjiang Kazakh general population.
