Diabetes-link genes found

The newly-discovered diabetes-link to the three genes bring the total number of genes known to be involved in type 2 diabetes to nine. Their exact role is still uncertain, scientists said, but two of them appear to be involved in the development and function of insulin-producing beta cells found in the pancreas.

Professor Mark McCarthy, of the University of Oxford, which took part in the study, said: "This research helps us to understand that, for most people at least, an individual's risk of developing diabetes as they get older is influenced by a number of genes, as well as by their environment."
