  schema:description "Loss of the succinate dehydrogenase enzyme, shown by a negative SDHB stain, marks a small family of tumours (some stomach GISTs, paragangliomas and phaeochromocytomas, a rare kidney cancer) that are often inherited, occur in young people, ignore imatinib and grow slowly; the stain is the trigger for germline testing of the whole family."@en ;
