MalaCards: Megacolon, also known as megacolon excluding hirschsprung's disease, is related to toxic megacolon and constipation. An important gene associated with Megacolon is SOX10 (SRY (sex determining region Y)-box 10), and among its related pathways is Gastrin-CREB signalling pathway via PKC and MAPK. The compounds cinanserin and clotiapine have been mentioned in the context of this disorder. Affiliated tissues include colon, smooth muscle and spinal cord, and related mouse phenotypes are hearing/vestibular/ear and vision/eye.

Disease Ontology:9 A colonic disease that is characterized by an abnormal dilation of the colon.
