Publication Detail
Detecting Gene Duplications in the Human Lineage
Abstract
Gene duplications represent an important class of evolutionary events that is likely to have contributed to the unique human phenotype in the short evolutionary time since the human-chimpanzee divergence. With the availability of both human and chimpanzee genome drafts in high coverage re-sequencing assemblies and the high annotation quality of most human genes, it should now be possible to identify all human lineage-specific gene duplication events (human inparalogues) and a few pioneering studies have attempted to do that. However, the different levels of coverage in the human and chimpanzee's genomes assemblies, and the differing levels of gene annotation, have led to problematic assumptions and oversimplifications in the algorithms and the datasets used to detect human lineage-specific gene duplications. In this study, we have developed a set of bioinformatic tools to overcome a number of the conceptual problems that are prevalent in previous studies and have collected a reliable and representative set of human inparalogues. © 2010 The Authors Annals of Human Genetics © 2010 Blackwell Publishing Ltd/University College London.
