We review the problem of confounding in genetic association studies, which arises principally because of population structure and cryptic relatedness. Many treatments of the problem consider only a si...
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
由于许多教科书中关于连锁平衡的介绍，多是引用结论或是推导不太严谨，使学生在学习群体遗传学时对理解连锁平衡的原理感到困难。本文从遗传平衡的基本条件出发，通过较严谨的数学推导，介绍了两个基因座的连锁平衡条件、平衡过程等原理，供教师和学生在群体遗传学教学中参考。Abstract: Because linkage equilibrium is introduced by directly quo...
北京地区汉族人群21号染色体上5个STR基因座的遗传多态性 Genetic Polymorphisms of Five STR Loci on Chromosome 21 in Chinese Han Population

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...
X连锁隐性遗传聋哑（deaf-mute）家系的遗传学特征分析 Genetic Analysis in a Chinese Deaf-Mute Family with X linked Recessive Inheritance
聋哑 遗传性耳聋 X连锁 基因定位
2008/1/8
摘要
在进行中国人群的遗传性耳聋发病情况的调查中，发现了一个5代隔代遗传的聋哑家系（L021家系）。研究中调查家系成员64人，对其中的31人进行了系统的听力学检查,发现聋哑男性8位，听力表型为全聋及极重度聋,获得家系成员的血样31人份。家系图谱分析显示该家系为X连锁隐性遗传性耳聋家系，为先天性聋哑疾病分子病理机制的研究提供了模板。

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...
一个并指（趾）缺指（趾）家系的遗传分析The Genetic Analysis of a Family with Syndactyly and Adactylism

摘要
选取9个多态性STR基因座，应用多重PCR技术和聚丙烯酰胺凝胶电泳结合银染显色的方法，对33例病理学诊断为完全性葡萄胎的组织标本及夫妇双方外周血标本进行分子病理学分析研究，判定其DNA来源。结果表明，33例病理学上的完全性葡萄胎有27例DNA为单纯性父方来源，占81.8%(27/33)，其中，纯合子完全性葡萄胎为22例，占66.7%(22/33)，杂合子完全性葡萄胎5例，占15.1%(5/...
