| 摘 要： | 目的采用插入/缺失(Insertion/Deletion,InDel)多态性遗传标记,建立一种可用于中国汉族、回族、维吾尔族、蒙古族、藏族5个主要民族法医DNA鉴定的多重PCR系统。方法采用人类基因组浏览器和dbSNP数据库筛选具有高度遗传多态性的人类常染色体InDel标记,采用Primer 3软件设计多重PCR引物,通过复合荧光标记系统建立多重PCR扩增体系,采用该体系对汉、回、维、蒙、藏5个民族进行多态性调查。结果成功建立了一个包含30个InDel位点和Amelogenin性别鉴定位点的复合荧光多重PCR扩增体系,命名为InDel_typer30。多态性调查显示这30个InDel位点在上述5个主要民族中均呈高度遗传多态性,平均期望杂合度分别为:0.464、0.460、0.453、0.466和0.469,平均个人识别率分别为:0.595、0.585、0.586、0.589和0.595。该系统在5个民族中的累积个人识别率(CDP)均达到0.999999999996以上。结论 InDel_typer30是一种适用于中国汉、回、维、蒙、藏5个主要民族的法医DNA鉴定系统。

| Abstract: | Objective To develop a multiplex PCR system,using insertion/deletion(InDel) polymorphism markers,for forensic DNA identification among Han,Hui,Uighur,Mongolian and Tibetan populations in China.Methods Highly polymorphic InDel markers from human autosomes were selected using the Human Genome Browser in Galaxy system and dbSNP database.Multiplex PCR primer pairs of selected InDel markers were designed using Primer 3 software.The multiplex PCR system was developed using a five fluorescence dye labeling system.... |
