HLA-DRB1等位基因与中国北方地区汉族人2型糖尿病大血管病变的相关性研究

The association of HLA-DRB1 alleles with macrovascular complication of type 2 diabetics in Han race of Chinese north area

目的 :探讨HLA DRB1基因多态性与 2型糖尿病 (type 2diabetesmellitus,T2DM)大血管病变的关系。方法 :采用序列特异性引物聚合酶链反应技术 (polymerasechainreactionwithsequence specificprimers ,PCR SSP)检测了中国北方地区汉族人88例T2DM患者 ( 5 2例无并发症 ,36例合并大血管病变 )HLA DRB1等位基因多态性。结果 :T2DM患者至少存在 11种HLA DRB1等位基因 ,T2DM伴大血管并发症组HLA DRB1 0 3、HLA DRB1 0 90 12基因频率明显高于无并发症组 (P <0 .0 5 )。结论 :HLA DRB1基因中DRB1 0 3、DRB1 0 90

Objective:To study the relationship between HLA-DRB1 gene polymorphisms and macrovascular complication of type 2 diabetics. Methods:HLA-DRB1 alleles in 88 cases of type 2 diabetics, including 52 ones without complication and 36 ones with macrovascular complication, were examined by PCR-SSP. Results:There were at least 11 HLA-DRB1 alleles in type 2 diabetics. The HLA-DRB1 *03 and HLA-DRB1 *09012 gene frequencies of type 2 diabetics with macrovascular complication were significant higher than those without complication.Conclusion:HLA-DRB1 *03 and HLA-DRB1 *09012 alleles or their linkage disequilibrium genes may enhance the risk of the development of type 2 diabetes macrovascular complication.
