| 摘 要： | 目的：探讨HSP90B1基因多态性与中国汉族人群系统性红斑狼疮(SLE)易感性的关系。方法：从医院收集360例对照和360例SLE患者,按照年龄和性别进行匹配。利用Multiplex SNaPshot分型技术对SNP位点分型。采用基于错误发现率 (FDR) 标准的本杰明-汉伯格 (BH) 法进行多重检验校正。结果：显性模型分析发现rs1165681的基因型频率分布在对照组和SLE组之间存在统计学差异(Crude OR = 0.621, 95%CI = 0.450-0.856, P=0.004; Adjusted OR = 0.619, 95%CI = 0.449-0.855, P=0.004);隐性模型分析发现rs10778306 (Crude OR = 0.568, 95%CI = 0.328-0.984,P = 0.044; Adjusted OR = 0.570, 95%CI = 0.329-0.988, P = 0.045)、rs2722188(Crude OR = 0.227, 95%CI = 0.076-0.681, P = 0.008; Adjusted OR = 0.227, 95%CI=0.076-0.682, P=0.008) 的基因型分布在两组之间存在统计学差异。BH法校正后,rs1165681基因型分布在两组之间有统计学差异 (PBH = 0.044)。单倍型分析后CCATTAGGCAT(OR=0.323, 95%CI=0.154-0.680, P = 0.002)、CCCTTAGGCAC (OR = 1.324, 95%CI = 1.014-1.729, P =0.039)、TCCCTAGTCGC(OR = 0.465, 95%CI = 0.221-0.979, P = 0.039)和TTCTCGGGCAT(OR=0.443, 95%CI = 0.224-0.875, P = 0.016) 与SLE的发病风险有关;BH法校正后,CCATTAGGCAT在两组之间的分布有统计学差异(PBH = 0.028),其他单倍型均无统计学差异 (P>0.05)。结论：HP90B1基因多态性可能与中国汉族人群的SLE发病有关。
