摘  要:目的探讨江苏省居民电压依赖钾通道蛋白1(KCNQ1)基因多态性与2型糖尿病发病的关系。方法研究对象分别来自于江苏省无锡市2007年2型糖尿病队列研究和南通市2009年慢性非传染性疾病横断面调查,共有病例2925例和对照3281名,对其进行流行病学问卷调查及体格检查,并于清晨采集空腹10h静脉血5ml,应用TaqManOpenArray基因分型系统和i-PLEX Sequenom MassARRAY基因分型平台进行KCNQ1基因分型。分析调整年龄、性别和BMI后KCNQ1基因4个位点多态性与2型糖尿病发病风险的关系。结果调整年龄、性别和BMI后,KCNQ1基因rs2237897、rs2237892、rs2237895位点C等位基因的存在均增加了2型糖尿病的患病风险,相加模型的OR(95%CI)值分别为1.41(1.30—1.54)、1.35(1.24~1.47)和1.22(1.12~1.33)(P值均〈0.05)。按年龄、性别、BMI进行分层后,各层间rs2237897位点C等位基因增加了2型糖尿病的患病风险,≤56和〉56岁相加模型的OR(95%CI)值分别为1.39(1.22~1.59)、1.43(1.28~1.60);女性和男性的OR(95%cI)值分别为1.40(1.26~1.55)、1.44(1.26~1.66);BMI〈24kg/m2和≥24kg/m2的OR(95%CI)值分别为1.48(1.33~1.66)、1.34(1.17—1.53)(P值均〈0.05)。结论KCNQ1基因rs2237897、rs2237892、rs2237895位点多态性与江苏省汉族居民2型糖尿病的发生相关。Objective To study the association of polymorphisms in the potassium voltage-gated channel,KQT-like subfamily, member 1 (KCNQ1) gene with type 2 diabetes in Chinese population from Jiangsu province. Methods Subjects consisting of 2925 cases and 3281 controls were enrolled from a community based cohort study of type 2 diabetes in Wuxi in 2007 and a community based cross-sectional survey on chronic non-communicable disease in Nantong in 2009. Epidemiological questionnaire survey and physical examinations were conducted and 10 h overnight fasting blood samples of 5 ml were drawn for all subjects. Genotypes were determined by TaqMan OpenArray Genotyping System and i-PLEX Sequenom MassARRAY platform. The relationship between KCNQ1 gene polymorphism and risk of type 2 diabetes after adjustment for age, sex and body mass index (BMI) was analyzed. Results The C allele of rs2237897, rs2237892 and rs2237895 at KCNQ1 increased the risk of type 2 diabetes with adjusted OR (95% CI) value being 1.41 ( 1.30 - 1.54), 1.35 ( 1.24 - 1.47 ), 1.22 ( 1.12 - 1.33 ) respectively ( all P value 〈 0. 05 ) under the additive genetic model after adjusted by age, sex and BMI. Stratification analyses in additive genetic model showed that the C allele of rs2237897 increased the risk of type 2 diabetes in subgroups stratified by age ( ≤56 years and 〉56 years) ,sex (females and males) ,BMI ( 〈 24 kg/m2 and I〉 24 kg/m2) with OR (95% CI) value being 1.39 (1.22 - 1.59), 1.43 (1.28 - 1.60), 1.40 (1.26 - 1.55), 1.44 (1.26-1.66),1.48 (1.33 - 1.66), 1.34 (1.17 - 1.53) respectively (all P value 〈 0.05).Conclusion Polymorphisms of rs2237897 ,rs2237892 and rs2237895 in the KCNQ1 gene were associated with occurrence of type 2 diabetes among Jiangsu province population.
