Almost 26 million children and adults in the US have diabetes, while 79 million of us have pre-diabetes. Now, researchers have identified rare mutations in a gene that they say could prevent type 2 diabetes - the most common form of the disease - even in people who have risk factors for the condition.

The international research team, led by investigators from the Broad Institute of the Massachusetts Institute of Technology and Harvard, and the Massachusetts General Hospital, recently published the findings in the journal Nature Genetics.
