Paraganglioma and gastric stromal sarcoma syndrome

Carney Stratakis dyad

A familial syndrome characterised by gastrointestinal stromal tumours and paragangliomas, often at multiple sites. It is a very rare syndrome presenting at a young age. The gastric stromal sarcomas are multifocal and the paragangliomas are multicentric. The clinical spectrum of this syndrome varies widely, depending on the localisation and the size of the tumours. The vast majority of cases are due to germline mutations of the succinate dehydrogenase (SDH) subunit genes SDHB, SDHC and SDHD. Predisposition to developing these tumours is inherited in an autosomal dominant manner with incomplete penetrance.
