摘要 目的研究长沙地区人群Rh阴性个体RHD基因多态性的分布及血清学表型与RH基因型之间的关系。方法应用PCR-SSP技术检测长沙地区108名Rh阴性献血者的RHD基因和RHCE基因。结果 108例Rh阴性个体中,ccee表型66例、Ccee32例、CCee7例、CcEe2例、ccEe1例;108例Rh阴性个体中68例RHD基因外显子完全缺失、24例完整、16例部分缺失。吸收放散试验检测出21例RhD放散型。结论长沙汉族Rh阴性人群的RHD基因结构呈现多态性,常规血清学鉴定的RhD阴性者中存在较高比例的RhD放散型(Del型),且有可能带有完整的RHD基因。携带D基因的吸收放散试验阴性个体中具有C抗原者比例较高,但亦有cc表型存在,有别于文献中认为全属RhC抗原表达者的报告。
