PPARGC1A基因Thr394Thr/Gly482Ser多态性与2型糖尿病的关联研究

对344例2型糖尿病患者和307名正常人的PPARGC1A基因单核苷酸多态性rs2970847(Thr394Thr)和rs8192678(Gly482Ser)与2型糖尿病的关系进行了单标记和单体型关联分析以及Logistic回归分析。在单标记分析中,对照组与病例组Thr394Thr的基因型和等位基因频率有显著差异(基因型, P =0.006; 等位基因, P < 0.001); Logistic回归和单体型分析表明, Thr394Thr的AA基因型及Thr394(ACA)-Ser482单体型增加患2型糖尿病的风险。Gly482Ser的基因型和等位基因频率在对照组与病例组间无显著差异。PPARGC1A基因是湖北汉人的一个2型糖尿病易感基因。

Association study between PPARGC1A Thr394Thr/ Gly482Ser polymorphisms and type 2 diabetes

To investigate the association between single nucleotide polymorphisms (SNPs) rs2970847(Thr394Thr) and rs8192678(Gly482Ser) of peroxisome proliferators activated receptor gamma coactivator-1(PPARGC1A)gene and type 2 diabetes in Chinese Han population in Hubei. The Thr394Thr and Gly482Ser polymorphisms of the PPARGC1A gene were genotyped in 307 controls and 344 type 2 diabetes patients. Single marker/haplotype association analyses and logistic re-gression analysis were performed. Significant differences in genotypic and allelic frequencies were observed between cases and controls for the Thr394Thr polymorphism (genotype, P=0.006; allele, Plt;0.001). The genotype AA of the Thr394Thr polymorphism and the haplotype Thr394(ACA)- Ser482 were significantly associated with type 2 diabetes. No differences in the genotypic and allelic frequencies between cases and controls were found for the Gly482Ser polymorphism. PPARGC1A is a susceptibility gene for type 2 diabetes in Chinese Han population in Hubei.
