Abstract
目的 探讨湖北汉族人HLA-DRB1等位基因与大肠癌遗传相关性。方法 针对HLA-DRB1等位基因等2外显子多态性,设计23对引物的序列特异性引物聚合酶链反应,结合等位基因序列分析,检测了无亲缘关系的湖北籍汉族健康人136名及大肠癌患者72例的HLA-DRBB1基因。SAS软件进行数据处理。结果 湖北地区汉族人大肠癌患者与正常人比较,HLA-DRB1*0901等位基因分布频率0.2292vs0.1397(P<0.005,OR=2.1822),病因分数0.2483;DRB1*080X等位基因频率0.0139vs0.0809(P<0.01,OR=0.1481),预防分数0.1354。提示HLA-DRB1*0901,*080X分别与该地区汉族人大肠癌呈正关联或负关联,两组间HLA-DRB1其余等位基因分布频率,差异均无显著性。结论 HLA-DRB1*0.0901为湖北地区汉族人大肠癌的易感基因,而-DRB1*080X铡为其抵抗基因,上述两种等位基因结构得到了等位基因序列分析印证
