The identification of a new mutation associated with type 2 diabetes suggests abnormal sleep patterns could be linked to diabetes and high blood pressure. Scientists recently identified a mutation near a gene called MTNR1B that increases a person's risk of having high blood sugar and elevates the chance of type 2 diabetes by 20 percent. MTNR1B is part of a pathway that controls melatonin, the hormone that regulates the body's internal clock. The proximity of the mutation and the melatonin gene suggests high blood sugar and diabetes could be directly related to a disturbed sleep pattern. Join discussion...
