Abstract

Given the unprecedented tools that are now available for rapidly comparing genomes, the identification and study of genetic and genomic changes that are unique to our species have accelerated, and we are entering a golden age of human evolutionary genomics. Here we provide an overview of these efforts, highlighting important recent discoveries, examples of the different types of human-specific genomic and genetic changes identified, and salient trends, such as the localization of evolutionary adaptive changes to complex loci that are highly enriched for disease associations. Finally, we discuss the remaining challenges, such as the incomplete nature of current genome sequence assemblies and difficulties in linking human-specific genomic changes to human-specific phenotypic traits.

摘要

鉴于现在有了用于快速比较基因组的空前工具,对我们人类特有的遗传和基因组变化的识别和研究已经加速,我们正进入人类进化基因组学的黄金时代。在这里,我们概述了这些努力,重点介绍了最近的重要发现、已鉴定的不同类型的人类特有基因组和遗传变化的例子,以及显著的趋势,例如进化适应性变化定位于与疾病关联高度富集的复杂基因座。最后,我们讨论了一些仍存在的挑战,例如当前基因组序列组装的不完整性以及将人类特有基因组变化与人类特有表型特征联系起来的困难。
