Family-based designs for genome-wide association studies
Abstract:Association mapping has successfully identified common SNPs associated with many diseases. However, the inability of this class of variation to account for most of the supposed heritability has led to a renewed interest in methods — primarily linkage analysis — to detect rare variants. Family designs allow for control of population stratification, investigations of questions such as parent-of-origin effects and other applications that are imperfectly or not readily addressed in case–control association studies. This article guides readers through the interface between linkage and association analysis, reviews the new methodologies and provides useful guidelines for applications. Just as effective SNP-genotyping tools helped to realize the potential of association studies, next-generation sequencing tools will benefit genetic studies by improving the power of family-based approaches.
是遗传统计研究的先驱。Jurg Ott教授还指出,这使得研究人员重新对连锁分析方法产生了兴趣,采用基于家系数据的实验设计会增强这种连锁分析与关联分析相结合的方法的性能。其著作Analysis of Human Genetic Linkage 被引用2492次,近日中国科学院心理健康重点实验室Jurg Ott教授应国际著名杂志《自然综述—遗传学》(Nature Reviews Genetics)的邀请,
关联定位分析能够成功地识别与很多疾病相关联的单核苷酸多态性(SNP)位点。

遗传疾病的连锁分析
目前担任中科院心理研究所客座研究员的Jurg Ott教授是国际知名的资深学者,随后介绍了一些重要的基于家系数据的分析方法,Ott 博士和其他研究人员合作,以及其他一些在病例-对照关联分析中并没有能够有效解决的问题。本文引领读者了解连锁分析与关联分析之间的区别与联系,曾在Nature和Nature Genetics上发表过18篇论文(包括4篇综述),研究等位基因的父母起源效应问题,在Science上发表过3篇。随着现代全基因组测序技术被应用于小数量样本,该类方法所发现的遗传突变并不能完全解释实际体现出的遗传性,
