Gastrointestinal stromal tumor (GIST) is characterized by KIT or PDGFRA gene mutation. Although chromosomal losses of 22q are frequent in GIST, it is unclear which tumor suppressor genes might be inactivated in association with such losses. The INI1 gene, located at 22q11.23, is a tumor suppressor gene that is frequently altered in malignant rhabdoid tumor.
