      Case: Sex Unknown, Age Unknown, Ethnicity Unknown

      DiseaseAssertion: VHL

      FamilyInfo: N/A

      CohortInfo: The authors evaluated 64 VHL patients (32 women and 32 men) with renal involvement of whom 54/64 had undergone renal surgery or a radiofrequency thermal ablation procedure for RCC. In 10/64 VHL patients, at least one or more RCC were diagnosed, however at the time of diagnosis an indication for treatment was not yet present. For all patients several CT/MRI scans existed for retrospective description of tumour growth kinetics.

      CasePresentingHPOs: HP:0005584 (Renal cell carcinoma)

      CaseHPOFreeText: This is a tumor resolution study (VHL patients were investigated based on the presence of renal tumors.) No other phenotypic information is available.

    1. Von Hippel-Lindau (VHL) is a tumor suppressor that negatively regulates the production of angiogenic factors. Mutations in the VHL gene cause VHL syndrome, which is characterized by highly vascularized tumors. Here we report a c.464T>A mutation of the VHL gene in three patients with hemangioblastoma from a Chinese family. This mutation was not reported previously and was absent in the unaffected family members. The mutation is predicted to cause Val to Glu substitution at VHL protein residue 155 in a conserved region. Previous biochemical studies demonstrated that residue Val-155 was critical for VHL protein binding to chaperonin TRiC/CCT, an essential step for proper VHL protein folding. Our finding of naturally occurring VHL V155E mutation in patients with VHL syndrome supports the functional importance of Val-155 residue in VHL protein and illustrates the diversity of VHL gene defects underlying VHL syndrome.

      PatientID: III-1

      KindredID: 1

      Case: F, 26Y0M, Chinese

      DiseaseAssertion: assumed VHL

      FamilyInfo: 10 members of this Chinese family were tested, and 3 were found with the same genetic mutation (c.464T>A). The proband’s grandmother (I-1, 79Y), and father (II-1, 53Y) had hemangioblastomas, and tested positive for the mutation. This mutation was not found in the other unaffected members in the family.

      CaseHPOFreeText: patient suffered with dizziness and headache and frequent vomiting since 25Y (CT and MRI identified occupying lesions and obstructive hydrocephalus in the cerebellar vermis). The cerebellar tumor nodes were removed surgically. Abdominal CT showed multiple lesions in the liver, pancreas and posterior peritoneum. The tumors in the proband’s pancreatic tail and retroperitoneal space also were removed subsequently. Histological analysis indicated the tumors to be pancreatic isletcell tumor and phaeochromocytoma, respectively.
