A faster and more accurate method of identifying which of an individual’s genes are associated with particular symptoms has been developed by a team of researchers from the UK and Saudi Arabia. This new approach could enable scientists to take advantage of recent developments in genome sequencing to improve diagnosis and potential treatment options.
Several major studies, published today, concur that virtually all current global human populations stem from a single wave of expansion out of Africa. Yet one has found 2% of the genome in Papuan populations points to an earlier, separate dispersal event – and an extinct lineage that made it to the islands of Southeast Asia and Oceania.
