Discovery of a novel heart and gut disease.

Physicians and researchers at CHU Sainte-Justine, Université de Montréal, CHU de Québec, Université Laval, and Hubrecht Institute have discovered a rare disease affecting both heart rate and intestinal movements. The disease, which has been named “Chronic Atrial Intestinal Dysrhythmia syndrome” (CAID), is a serious condition caused by a rare genetic mutation. This finding demonstrates that heart and guts rhythmic contractions are closely linked by a single gene in the human body, as shown in a study published on October 5, 2014 in Nature Genetics.
