PatientID: None (Cousin 2)

KindredID: G

Case: Sex Unknown, 38Y0M, Hungarian

DiseaseAssertion: Assumed VHL

FamilyInfo: Large VHL family spanning five generations. The index patient presented with pheochromocytoma, renal cell carcinoma as well as spinal cord, cerebellar, and medulla oblongata hemangioblastomas. Her parents showed no clinical, biochemical, or radiological evidence of the disease, but VHL-associated tumors were detected in five other family members (bilateral renal cell carcinomas in one, renal cysts in one, spinal cord, cerebellar, and medulla oblongata hemangioblastomas in three, retinal hemangioblastomas in four, and pheochromocytomas in two family members).

CasePresentingHPOs: HP:0010797; HP:0009711; HP:0002666 (Hemangioblastoma, Retinal capillary hemangioma, Pheochromocytoma)

CaseHPOFreeText: Presented with CNS hemangioblastoma at age 38, pheochromocytoma at age 39 and retinal hemangioblastoma at age 29. No VHL diagnosis noted but assumed to have VHL based on genetic, clinical and familial findings.

Case: M, 29Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: First cousin (male, 33Y) presented with CNS hemangioblastoma, RCC, optic atrophy, vision loss and retinal capillary hemangioblastoma. THis cousin also had the same germline mutation as the proband.

CasePresentingHPOs: HP:0005584; HP:0011531; HP:0009711; HP:0000541 (Renal cell carcinoma, Vitritis, Retinal capillary hemangioma, Retinal detachment)

CaseHPOFreeText: About 1 month previously, percutaneous radiofrequency ablation treatment was performed on the patient due to RCC in his left kidney. Vitritis was detected in the right eye on slit-lamp biomicroscopy. The fundus examination revealed an extensive lipid exudation on the fovea and macula, and a 3-4 optic disc diameter-sized RH at the equator in the right eye; it was normal in the left eye. Optical coherence tomography (OCT) showed that there was a foveal detachment in the right eye.

CaseNotHPOs: HP:0100006 (Neoplasm of the central nervous system)

CaseNotHPOFreeText: Central nervous system involvement was not detected in the patient.
