Overview
Causes
Most GISTs are sporadic. Less than 5% occur as part of hereditary familial or idiopathic multitumor syndromes. These include, in descending order of frequency, neurofibromatosis Recklinghausen (NF-1), Carney's triad (gastric GIST, pulmonary chondroma and extra-adrenal paraganglioma), germline gain-of-function mutations in c-Kit/PDGFRA, and the Carney-Stratakis syndrome.
[1] The Carney-Stratakis syndrome is a dyad of hereditary GIST and paraganglioma, that is caused by germline mutations in the mitochondrial tumor suppressor gene pathway involving the succinate dehydrogenase (SDH) subunits SDHD, SDHC and SDHB. Carney's triad does not feature SDH mutations.
