摘要 目的探讨HLA—DM基因多态性分布,为研究Ⅱ类分子相关疾病奠定基础。方法采用PCR-RFLP法检测143例南方汉族人HLA—DM基因多态性及基因型。结果DMA女0101—0104等位基因频率分布依次为77.97%、18.18%、2.45%、1.40%;DMB*0101~0104等位基因频率分布依次为72.03%、19.58%、5.24%和3.15%。DMA基因型分布频率较高者为DMA*0101/0101和0101/0102,频率分别为62.94%、25.17%;DMB基因型分布频率较高者为DMB*0101/0101、0101/0102,频率分别为54.55%、26.57%。结论南方汉族人中HLA—DM等位基因频率分布以HLA-DMA%0101—0102、HLA—DMB*0101~0103为主;DM基因型分布以DMA*0101/0101、0101/0102和DMB*0101/0101、0101/0102为主;本研究结果为研究Ⅱ类分子相关疾病奠定了基础。
