Bringing the known number to a grand total of 38 is yet another dozen new genes that scientists have identified and linked to the most common form of diabetes.
Researchers at Edinburgh University hope to search for better ways of preventing and treating the Type 2 diabetes, which alters levels of insulin, the body's sugar-regulating hormone.
The genes are involved in the function of insulin-producing pancreatic cells, the control of insulin's action in the body, and the regulation of cell growth.
According to Dr Jim Wilson, a member of the research team from the University of Edinburgh, regulation of these genes can lead to many different diseases because they contain variants that increase the risk of unrelated diseases, including skin and prostate cancer, coronary heart disease and high cholesterol.
The research was published yesterday in the journal Nature Genetics.
