      PatientID: Proband

      KindredID: 9

      Case: M, 47Y0M, Korean

      DiseaseAssertion: VHL

      FamilyInfo: Niece presented with the same variant and CNS hemangioblastoma at 14Y, bilateral retinal hemangioblastoma at 26Y, RCC at 32Y, multiple pancreatic lesions (pancreatic cyst or tumor, unspecified) at 26Y and bilateral renal cysts at 32Y. Brother had a history of CNS hemangioblastoma but was not genetically confirmed.

      CohortInfo: Thirteen unrelated patients with germline VHL mutations who were diagnosed with VHL disease were evaluated.

      CaseHPOFreeText: Presented with dizziness and headache, which he had experienced for the 3 months prior to examination. CNS hemangioblastoma at 47Y, RCC at 47Y, multiple pancreatic lesions (pancreatic cyst or tumor, unspecified) at 47Y, renal cyst at 48Y and pheochromocytoma at 47Y. Diagnosed with VHL Type 2B.
