PatientID: III:4

KindredID: 1

Case: M, 56Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: A 5-generation family with VHL in 15 members. Both second generation children (presumed), 5 third generation, and 8 further generation individuals were affected and haplotyping was conducted using three polymorphic microsatellite markers. All of the 5th generation children (9 total at time of publication) had been sequenced and haplotyped as unaffected.

CasePresentingHPOs: HP:0006880; HP:0002666 (cerebellar hemangioblastoma; pheochromocytoma)

CaseHPOFreeText: patent had a combination of cerebellar HB and bilateral pheo, age of onset at 38Y, and operated on the same year

Case: M, 38Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband (patient 81) had 3 family members confirmed with the mutation: his aunt 2 (patient 85) had pancreatic cysts and/or tumors at age 50, his cousin/ the son of Aunt 2 was asymptomatic at the time of assessment, and the granddaughter of aunt 2 was also asymptomatic at the time of assessment. The proband also had 3 family members who passed away before diagnosis/ before confirming the mutation: his mother (patient 82) had a CNS hemangioblastoma at 33, his Aunt 1 (patient 83) had a CNS hemangioblastoma at 32, and his cousin/ the son of Aunt 1 (patient 84) had a CNS hemangioblastoma at 30.

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.
