VHL Gene Sequencing & Del/Dup


Genes

VHL

Conditions

  • Von Hippel-Lindau syndrome

Clinical Utility

  • An individual with a personal history and family history of tumors or other clinical features associated with Von Hippel-Lindau (VHL), such as Hemangioblastomas of the spine, brain or retina; renal and/or pancreatic cysts; renal cell carcinoma; pheochromocytomas; pancreatic neuroendocrine tumors; epididymal cystadenomas; endolymphatic sac tumors
  • An individual with early-onset renal cell carcinoma OR renal cancer at any age and a personal or family history of any other features associated with VHL
  • An individual with multiple hemangioblastomas of spine, brain, or retina OR a single hemangioblastoma and a personal or family history of other features associated with VHL
  • An individual with a pheochromocytoma, especially if young and/or bilateral.
  • An individual with a multiple renal and pancreatic cysts and a family history of other features associated with VHL
  • An unaffected individual with a family history suggestive of VHL (see above) when an affected individual is unavailable for his or her own genetic testing
