摘　　要：目的建立筛选线粒体DNA异质性的DHPLC方法;检测线粒体DNA高变区的异质性频率。方法选取尸体18例,分别提取血、心、肝、脾、肺、肾、胰腺、脑、肌肉、皮肤、肋骨、指甲及毛发的mtDNA,用DHPLC筛选异质型样本,并用直接测序法进行验证。结果9例个体存在异质性,肌肉组织出现的异质性频率最高。结论正确认识线粒体DNA异质性对于法医学应用领域具有指导意义。Objective To establish the method of screening mtDNA heteroplasmy by DHPLC, and to investigate the frequency of mtDNA heteroplasmy in control region within multiple tissues of the same individual, it is provided reference by use of mtDNA technology in forensic community. Method Select blood, heart, liver, spleen, lung, kidney, pancreas, brain,muscle,skin,rib, nail and hair of 18 individuals, screening the heteroplasmyic samples by DHPLC,and confirm by direct sequencing. Result 9 het eroplasmic individuals were detected,the frequency of heteroplasmy is highest in muscle tissue. Conclusion It is important to take into account mtDNA heteroplasmy in forensic applied field.
