This is the blog for GW students taking Human Evolutionary Genetics. This site is for posting interesting tidbits on: the patterns and processes of human genetic variation;human origins and migration; molecular adaptations to environment, lifestyle and disease; ancient and forensic DNA analyses; and genealogical reconstructions.

Non-potluck post from The American Journal of Human Genetics: Natural Selection on Genes Related to Cardiovascular Health in High-Altitude Adapted Andeans


Natural Selection on Genes Related to Cardiovascular Health in High-Altitude Adapted Andeans
In this paper, the authors demonstrate how different populations living in similar condition can adapt to high altitude through different pathways. Unlike Tibetan highlanders adapted to high altitude via the selection of genetic variants associated with reduced polycythemic response to hypoxia, this study shows that Andeans adapt to high altitude through other mechanisms. A whole-genome sequencing showed the strongest evidence of selection of BRINP3, NOS2, and TBX5, which were also associated with cardiovascular development and function, but not in response to hypoxia. Using the association mapping, they found that this selection might be associated with phenotypic variations related to cardiovascular health.
