Intragenus (Homo) variation in a chemokine receptor gene (CCR5).

ABSTRACT: Humans have a comparatively higher rate of more polymorphisms in regulatory regions of the primate CCR5 gene, an immune system gene with both general and specific functions. This has been interpreted as allowing flexibility and diversity of gene expression in response to varying disease loads. A broad expression repertoire is useful to humans-the only globally distributed primate-due to our unique adaptive pattern that increased pathogen exposure and disease loads (e.g., sedentism, subsistence practices). The main objective of the study was to determine if the previously observed human pattern of increased variation extended to other members of our genus, Homo. The data for this study are mined from the published genomes of extinct hominins (four Neandertals and two Denisovans), an ancient
