    Mutation screening of VHL gene in a family with malignant bilateral pheochromocytoma: from isolated familial pheochromocytoma to von Hippel-Lindau disease
    1
    1. ClingenBaseline 05 Nov 2026
      In this paper we report the presence of a single nucleotide mutation in exon 3 of VHL gene c499 C>T causing substitution of Arginine by Tryptophan at position 167 (R 167 W).

      PatientID: 1 (III:1)

      KindredID: 1

      Case: F, 39Y0M, Persian

      DiseaseAssertion: VHL

      FamilyInfo: 4 sisters were treated with bilateral adrenal mass resection. Patient 2 died at 23Y and patient 3 died at 21Y due to complications associated with VHL. 2 years later, 3 of their other sisters were found to have the mutation. It is assumed that all 5 of them had the VHL mutation. Their mother and the siblings examined normal, and the father had passed earlier and had a family history of hypertension.

      CasePresentingHPOs: HP:0002666; HP:0009711 (pheochromocytoma; retinal capillary hemangioma)

      CaseHPOFreeText: Presented with cerebral hemorrhage and coma at the age of 29 years. Bilateral malignant pheochromocytoma (adrenal mass resection) and retinal angiomas. Malignant pheochromocytoma confirmed with biochemical tests and pathology with involvement of liver, pancreas, kidneys and inferior vena cava.
