Researchers develop a test for newly identified heart and gut disease

History and science have joined forces. Canadian researchers have discovered and identified a heart and gut disease caused by a genetic mutation that can be traced back to the 12th century Vikings. The disease, named Chronic Atrial Intestinal Dysrhythmia syndrome (CAID) is a severe condition caused by the mutation, but researchers were able to develop a diagnostic test for the syndrome. Patients with the syndrome require intensive treatment, often including implanting a pacemaker and bowel surgeries. The French Canadian and Scandinavian patients were traced back to the same ancestors, who dispersed globally after centuries of Viking migration. Release
