宁夏回族原发性高血压人群HLA-DQB1基因多态性分析

目的：分析HLA-DQB1基因多态性在宁夏回族人群原发性高血压（EH）患者中的分布，阐明宁夏回族人群原发性高血压的易感性。方法：采用序列特异性引物聚合酶链式反应（SSP-PCR）的方法对宁夏回族66例健康个体(对照组)及84例EH患者(病例组)的HLA-DQB1位点进行基因分型，应用遗传学统计方法分析宁夏回族原发性高血压人群DQB1基因多态性。结果：病例组等位基因DQB1*0301、*0401、*0601、*0604/5/6/7、*0302频率显著高于对照组（P<0.01或P<0.05）；病例组等位基因DQB1*0501、*0602、*0603/8、*0606、*0402、*0604/5/6/8频率显著低于对照组（P<0.01或P<0.05）。结论：DQB1*0301、*0401、*0601、*0604/5/6/7、*0302与宁夏回族人群原发性高血压的易感性有关，而DQB1*0501、*0602、*0603/8、*0606、*0402、*0604/5/6/8有可能是宁夏回族人群原发性高血压的保护因子。

Analysis on polymorphisms of HLA-DQB1 gene in Ningxia Hui polulation with essential hypertension

Objective To investigate the susceptibility to essential hypertension(EH) in Ningxia Hui population based on the distribution of the polymorphisms of HLA-DQB1 in EH population. Methods PCR-SSP method was conducted to examine the genotypes of HLA-DQB1 in 66 healthy individuals and 84 EH patients,and the genotypic and allelic frequencies were statistically computed. Results The distribution of alleles was significantly different between two groups.The frequencies of *0301,*0401,*0601,*0604/5/6/7,*0302 in EH g...
