The aim is to identify DNA variants which play a role in susceptibility or resistance to these diseases. There may be variants that make it more likely that you will get type 2 diabetes, and other variants that have a protective effect against the same disease. With most of these diseases, we understand little about the causes. If we can learn that this gene makes you more or less susceptible, we get important clues as to how the disease works.
