Scientists just drew the most detailed map yet of how your DNA shapes disease. Three studies from Australia's Garvan Institute analyzed gene activity in over 5 million immune cells from nearly 2,000 people, linking genetic variants to 16 diseases and uncovering nearly 1,500 genes that may drive conditions from cancer to neurological disorders. The findings could supercharge drug discovery and precision medicine.
Australian researchers have published three landmark studies in Nature, delivering the most detailed map to date of how genetic variation shapes immune cell function and drives disease. The work, led by the Garvan Institute of Medical Research in collaboration with the Murdoch Children's Research Institute and UNSW, is the first major output of the TenK10K project — an ambitious effort to map genetic variation and gene activity in immune cells from 10,000 people.
By sequencing the genomes of nearly 2,000 Australians and measuring gene activity across more than 5 million immune cells, the team linked genetic variants to 16 diseases — including cancers, immune conditions, and neurological disorders — and identified nearly 1,500 potentially causal genes. Crucially, many of these mechanisms were invisible to prior studies because they only appear in specific immune cell types, not across all blood cells.
By the Numbers:
Why it matters: Knowing which genetic variant drives a disease, in which cell, and through which mechanism is the key to identifying patients likely to respond to specific treatments — and to developing drugs against targets we didn't even know existed. All summary results are freely available to accelerate global research.
