The 47 people are anonymous, having consented for their genomes to be used as part of a previous project. The group, called the Human Pangenome Reference Consortium, said they have now compiled the genomes of 47 people from different backgrounds - and plan to increase that number to 350 by the middle of next year. ![]() Being alone zaps energy from humans, scientists say.In a series of papers published in the journal Nature, a large team of international researchers described the first draft of a more inclusive "pangenome" reference that they say more accurately reflects humanity. This meant it had many gaps and did not work as well as a reference for people from other ethnicities and races, prompting concerns about bias and inequality. However, 70 percent of the genetic data for this original genome reference came from a single person - a man who answered a newspaper advert in Buffalo, New York in 1997 - with snippets from 20 others. The breakthrough allowed scientists to identify genes that cause specific diseases, paved the way for the still-growing field of personalized medicine, and shed new light on human evolution. The first human genome was sequenced in 2003, providing a reference point for all other human sequences to be compared to. ![]() The announcement was hailed by researchers as a major scientific milestone that "heralds a new age of genetic diagnosis". ![]() PARIS-Scientists on Wednesday unveiled the first draft of a human "pangenome", a more diverse and accurate DNA blueprint for our species that they hope will help shed light on a range of diseases.
