PatientID: 1

KindredID: 1

Case: F, 44Y0M, Ethnicity Unknown

DiseaseAssertion: assumed VHL

FamilyInfo: The patient has a notable family history. Her eldest brother had multiple RCCs in both kidneys, bilateral cerebellar hemangioblastomas, and pheochromocytoma in his left adrenal gland (see Patient 2). Her daughter also underwent cortex-sparing adrenalectomies for bilateral pheochromocytomas as well as hemangioblastoma resection in her left cerebellum at age of 19 years, although no testing for VHL was stated.

CasePresentingHPOs: HP:0006748, HP:0030405, HP:0006880, HP:0000107, HP:0005584 (adrenal pheochromocytomas, pancreatic endocrine tumour, cerebellar hemangioblastoma, renal cyst, renal cell carcinoma)

CaseHPOFreeText: Patient diagnosed at age 29 with bilateral pheochromocytomas when she presented with severe hypertension and two large masses (greater than 6 cm) in her bilateral adrenal glands. At 38 years old, she underwent a resection for a mass found on her pancreas, with pathological analysis of the mass revealing a pancreatic neuroendocrine tumor. At 42 years old, a follow-up CT scan revealed two heterogeneous contrast-enhanced masses, one on the right kidney and one on the left adrenal gland.

FamilyInfo: Proband (patient 42) has four family members confirmed with the mutation, and two family members who passed away before diagnosis/ genetic confirmation of the mutation. Family members confirmed with the mutation include: the proband's daughter (patient 43) who had retinal angioma (age 17), renal cell carcinoma (21), multiple pancreatic cysts/tumors (18), and a pheochromocytoma (19). His son (patient 44) who was asymptomatic at the time of assessment. His niece 1 (patient 47) who had a retinal angioma and renal cell carcinoma (22). And his niece 2 (patient 28) who had a CNS hemangioblastoma (19) and a retinal angioma (18). Family members who passed away before diagnosis and were not genetically confirmed include: his sister (oatient 45) who had a CNS hemangioblastoma (22), and his brother (patient 46) who had a retinal angioma and renal cell carcinoma at 52.
