Von Hippel-Lindau disease.

Germline mutations in the VHL tumour suppressor gene may cause a variety of phenotypes including von Hippel-Lindau (VHL) disease, familial phaeochromocytoma and inherited polycythaemia. VHL disease is a multisystem familial cancer syndrome and is the commonest cause of familial renal cell carcinoma (RCC). VHL disease provides a paradigm for illustrating how studies of a rare familial cancer syndrome can produce advances in clinical medicin and important insights into basic biological processes. Thus the identification of the VHL gene has improved the diagnosis and clinical management of VHL disease and provided insights into the pathogenesis of sporadic clear cell RCC. Functional investigations of the VHL gene product have provided novel information on how cells sense oxygen and the role of hypoxia-response pathways in human tumourigenesis. Such information offers prospects of novel therapeutic interventions for VHL disease and common cancers including RCC.
