Abstract:
Objective To study the association of TCF7L2 gene rs11196218,rs290487 polymorphisms with metabolic syndrome in type 2 diabetes mellitus population.Methods According to the diagnostic criteria of international diabetes federation (IDF),680 cases of type 2 diabetes patients were divided into metabolic syndrome (MS) group and non metabolic syndrome (control) group.DNA was extracted from peripheral mononuclear cells,and then PCR was performed to specifically amplify TCF7L2 gene fragments.Gene polymorphisms were determined by connected enzyme detection reaction.After population representative was checked by Hardy-Weinberg equilibrium,statistical analysis was completed by software SPSS 13.0.Results The population was accorded with Hardy-Weinberg equilibrium and possessed the population representative.Frequency distributions of genotypes (GG,AG and AA) in TCF7L2 gene rs11196218 in MS and control groups were 55.6％(233/419),35.8％(150/419),8.6％ (36/419) and 54.8％ (126/230),39.1％ (90/230),6.1％ (14/230),respectively.Frequency distributions of alleles(G and A) in TCF7L2 gene rs11196218 in MS and control groups were 73.5％(616/838),26.5％(222/838)and 74.3％(342/460),25.7％(118/460),respectively.Frequency distributions of genotypes (GG,AG and AA) in TCF7L2 gene rs290487 in MS and control groups were 14.8％(62/418),42.3％(177/418),42.9％(179/418) and 15.0％(34/226),48.2％(109/226),36.8％(83/226),respectively.Frequency distributions of alleles(G and A) in TCF7L2 gene rs11196218 in MS and control groups were 36.0％ (301/836),64.0％ (535/836) and 39.1％ (177/452),60.9％ (275/452),respectively.Frequency distribution of allele and genotype in TCF7L2 genes rsl 1196218 and rs290487 between the two groups were not associated with metabolic syndrome in type 2 diabetes population (P ＞ 0.05).Conclusions TCF7L2 gene rs11196218,rs290487 polymorphisms has not association with metabolic syndrome of type 2 diabetes.
