Intussusception, also known as invagination of intestine or colon, is related to intestinal obstruction and lipomatosis, familial multiple. An important gene associated with Intussusception is STK11 (Serine/Threonine Kinase 11), and among its related pathways/superpathways are ERK Signaling and Signal Transduction. The drugs Vaccines and Immunologic Factors have been mentioned in the context of this disorder. Affiliated tissues include colon and small intestine, and related phenotypes are intussusception and homeostasis/metabolism
