Von Hippel-Lindau syndrome

Von Hippel-Lindau syndrome (VHL) is a hereditary cancer predisposition syndrome with a reported prevalence between 1:36,000 and 1:85,000. VHL is characterized by an increased risk for central nervous system hemangioblastomas (60–80%), retinal capillary hemangiomas (50–60%), renal cysts and carcinomas (30–60%), pancreatic cysts (30–65%), pheochromocytomas (11–19%), epididymal cystadenomas (26%), and endolymphatic sac tumors (2–10%).1 Clinically, VHL families can be subdivided on the basis of absence (Type 1) or presence (Type 2) of pheochromocytoma (PCC). Patients with VHL type 1 are at high risk for hemangioblastoma (HB) and renal cell carcinoma (RCC) and low risk for PCC. Patients with VHL type 2A have an increased risk for HB and PCC, but low risk for RCC. VHL type 2B are at high risk for HB, RCC and PCC while type 2C are at low risk for HB and RCC and high risk for PCC. VHL is highly penetrant and all individuals who harbor a mutation in the VHL gene will develop symptoms by 65 years of age. However, the clinical manifestations and disease severity are highly variable, even among family members with the same mutation.

Test Details

VHL
  • 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
  • Capillary Sequencing
