Washington: Scientists have decoded the genomes of more than 1,000 people from 14 ethnic global groups, in the largest and most detailed compilation yet of human DNA variations, to trace rare and common diseases to their very roots.The 1,000 Genomes Project involved some 200 scientists at Washington University School of Medicine in St. Louis and other institutions. Eventually, the initiative will involve 2,500 individuals from 26 populations.The raw information thrown up by the gigantic project took up some 180 terabytes of hard-drive space, enough to fill more than 40,000 DVDs. All of the information is freely available on internet, the journal Nature reported."With this resource, researchers have a road map to search for the genetic origins of diseases in populations around the globe," said co-principal study investigator Elaine Mardis, co-director of the Genome Institute at Washington University.
