Gastrointestinal stromal tumor (GIST) GISTs start in specialized nerve cells located in the walls of your digestive system. These cells are part of the autonomic nervous system. A specific change in the DNA of one of these cells, which control such digestive processes as movement of food through the intestines, gives rise to a GIST.
