      PatientID: None

      KindredID: 1

      Case: F, 48Y0M, Ethnicity Unknown

      DiseaseAssertion: Assumed VHL

      FamilyInfo: The patient’s aunt presented with Hodgkin’s lymphoma at 38Y and was deceased at 40Y. The patient’s father presented with liver cancer at 72Y and was deceased at 74Y. Additionally, the patient’s deceased grandfather had an unspecified cancer. The patient’s son presented with unilateral pheochromocytoma at 13Y. The patient’s daughter presented with pheochromocytoma at 12Y, and bilateral retinal hemangioblastoma, right adrenal pheochromocytoma, and islet cell neuroendocrine carcinoma of the pancreas with nodal metastasis at 20Y, and was found to carry the mutation the patient carried.
