UK researchers are to analyse thousands of DNA samples in a bid to find genetic signposts for eight major diseases. The collaboration of 24 leading human geneticists, is to receive £9m in funding from the Wellcome Trust. They will look at TB, heart disease, type 1 and 2 diabetes, arthritis, Crohn’s disease, ulcerative colitis, bipolar disorder and hypertension. It is hoped the project will lead to better understanding of who is at risk, and the development of new treatments.
