Co-Principal Investigator Dr Luis Nacul, CureME Biobank, London School of Hygiene & Tropical Medicine, says: “Unlocking the genetic susceptibility to ME/CFS is a key part of understanding what causes ME/CFS and the disease mechanisms involved. This, in conjunction with other biomedical research into ME/CFS, should finally pave the way to better diagnosis and the development of specific treatments for this debilitating disease.”
