中国南方汉族人群6个Y-STR基因座遗传多态性及法医学应用Genetic Polymorphisms of 6 Y-Chromosome Specific STR Loci in the southern Chinese Han Population and Its Application in Forensic Science
Y染色体 短串联重复序列（STR） 单倍型 遗传多态性
2008/1/31
摘要
为研究中国南方汉族人群DYS393等6个Y-STR基因座的遗传多态性并用于法医学鉴定，通过采用PCR复合扩增和基因测序仪荧光检测方法，检查204个无关男性个体，调查南方汉族的6个Y-STR基因座的单倍型频率，并对93对真父子和38对非父子的亲子鉴定样本进行检测。结果DYS393基因座检出5个等位基因，DYS19基因座检出6个等位...
贵州地区汉族人群THO1、TPOX、CSF1PO基因座的遗传多态性Genetic Polymorphisms of STR Loci THO1、TPOX、CSF1PO in Guizhou Han Population
短串重复序列 聚合酶链反应 遗传多态性
2008/1/10
摘要
为了解贵州地区汉族群体中THO1、TPOX、CSF1PO基因座的遗传多态性，获得这3个基因座的群体遗传学数据和法医学相关数据。采自贵州地区汉族无关个体的110份EDTA抗凝血样用Chelex法提取DNA，应用PCR复合扩增技术扩增样本后，聚丙烯酰胺凝胶电泳分型。对3个STR基因座的等位基因频率进行了调查分析，并与其他汉族人群的等位基因频率进行了比较。在贵州汉族群体中，3个基因座的基因型分...

摘要
阐明21号染色体上唐氏综合征关键区域内或附近的5个STR基因座（D21S1413、D21S1446、D21S1437、D21S1411、D21S1412）在北京地区汉族人群中的结构特征和群体遗传学数据。Chelex法提取血DNA，PCR扩增后，应用聚丙烯酰胺凝胶电泳和银染法或基因片段扫描检测法进行STR分型，测序后确定STR基因座的主型和进行等位基因的命名。结果该5个STR基因座具有简单重...
中国广东汉族人群核苷酸修复基因hMTH1遗传多态性研究Genetic Polymorphisms of Nucleotide Repair Gene hMTH1 in Southern Chinese Han Population
hMTH1基因 遗传多态性 聚合酶链反应 单链构象多态性
2008/1/6
摘要
为研究中国南方汉族人群核苷酸修复基因hMTH1遗传多态性，应用聚合酶链反应-单链构象多态性技术检测172名健康人外周血白细胞hMTH1基因启动子及全部5个外显子多态性，并进行DNA测序。结果发现hMTH1基因启动子及外显子1序列保守，未见突变；外显子2第73位碱基存在T→C杂合型突变，基因型TT和TC频率分别为93.02%、6.98%，等位基因T和C频率分别为96.51%、3.49％；外显...
