CaseHPOFreeText: Complained of a shadow in his right eye and was diagnosed with retinal detachment secondary to a retinal hemangioblastoma. MRI of the brain revealed a hyper vascular lesion in the medulla and a smaller lesion at the medullary-spinal cord junction. Weighted abdominal MRI revealed innumerable pancreatic cysts and multiple benign-appearing renal cysts. After surgical resection of the retinal hemangioblastoma, the patient remains asymptomatic.

FamilyInfo: Large multigenerational family with a history of both VHL and spinocerebellar ataxia type 2 (SCA2). Screening for clinical and genetic diagnostics were gathered as well as thorough information on non-living members. See family pedigree (Fig. 1).

CaseHPOFreeText: diagnosed with VHL in her early teenage years. She had retinal involvement beginning at the age of 13 treated by cryotherapy and laser therapy (presumably for retinal angiomas); and retinal detachment at the age of 23 requiring eye surgery. She had cysts of the pancreas and kidney detected at 22 years. She has also carried the diagnosis of OPCA since the age of 26-28 (new onset slurred speech and illegible handwriting). Patient had multiple renal cysts without renal tumours, however a large infiltrative enhancing mass in the tail of the pancreas was suggestive of a neuroendocrine/islet cell carcinoma, and liver metastatic foci

LegacyVariant: c.688delA

CaseProblemVariantFreeText: c.477del, p.Glu160Serfs10 should be used. Details: 477del same as 475delA bc that codon is AAA so doesn't matter which A gets deleted: there is an A at 475 476 477 so for HGVS we say that 477 (the latter) is deleted since that follows HGVS nomenclature. Thus use c.477del: p.Glu160Serfs10

Case: F, 22Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Index patient was a young woman who presented with cerebellar hemangioblastoma, multiple renal cysts, retinal detachment with vitreous hemorrhage, pancreatic cyst, spinal cord hemangiomas, and recurrence of the cerebellar lesion. Family members were not available for clinical and genetic screening, but family history revealed that the patient's father died of metastatic renal cell carcinoma.

CaseHPOFreeText: Patient underwent surgery for cerebellar hemangioblastoma at the age of 22 years. Multiple renal cysts and retinal detachment with vitreous hemorrhage were also observed. At the age of 26 years, pancreatic cyst, spinal cord hemangiomas, and recurrence of the cerebellar lesion were found. Diagnosed with VHL Type 1.
