摘要: 摘要:目的 研究CDKN2A/2B基因rs10811661的单核苷酸多态性(SNP),探讨其与妊娠糖尿病(GDM)的相关性。方法 选取鲁西南地区正常糖耐量孕妇(NGT)100例、GDM患者120例、2型糖尿病(T2DM)患者100例作为研究对象,提取基因组DNA,采用PCR-RFLP方法检测CDKN2A/2B基因rs10811661多态性,并进行统计学分析。结果 CDKN2A/2B基因rs10811661的TT、TC、CC三种基因型分布在NGT组与GDM组之间差别有统计学意义(P=0.005), GDM组危险等位基因T分布频率显著高于NGT组(P=0.012)。三种基因型及等位基因分布在NGT组与T2DM组之间差别亦有统计学意义(P分别为0.014,0.015)。但GDM组与T2DM组之间的基因型和等位基因频率分布差别没有统计学意义(P分别为0.733,0.536)。结论 在鲁西南地区女性人群中,CDKN2A/2B 基因rs10811661T/C多态性可能与妊娠糖尿病有明显相关性。

Abstract: Abstract: Objective To investigate the relationship between polymorphisms of rs10811661 in CDKN2A/2B gene and gestational diabetes. Methods The 100 normal glucose tolerance pregnant women, 120 gestational diabetes patients and 100 type 2 diabetes patients living in the southwest of Shandong Province were recruited. Using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism, we determined the genotypes of rs1081166 in CDKN2A/2B. Results There were significant difference in genotypic TT, TC ,CC and risk allele T frequency of CDKN2A/2B rs10811661 between NGT group and GDM group(P=0.005, 0.012respectively). So did the difference between NGT group and T2DM group(P=0.014, 0.015 respectively).But there were no difference between GDM group and T2DM group. Conclusion The rs10811661 T/C polymorphisms of CDKN2A/2B gene may be related with the gestational diabetes patients in the the southwest of Shandong Province.
