KindredID: 50

Case: F, 45Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband (patient 132) had multiple family members who were unconfirmed with the mutation. Her brother 1 (patient 133) had a CNS hemangioblastoma at 29, and renal cell carcinoma and multiple pancreatic cysts/tumors at 48; however no DNA sample was available for testing. Her brother 2 (patient 134) had a CNS hemangioblastoma at 27, but passed away before he could be genetically confirmed with the mutation. Similarly, her father (patient 135) had a CNS hemangioblastoma at 25, but passed away before he could be genetically confirmed.

CaseHPOFreeText: Presented at age 39 with bilateral renal tumors (2 right side, 3 left side). Pathological evaluation revealed clear cell type renal cell carcinoma (fig. 1, B). After 2 years multiple pancreatic cysts were noted. Two years later 6 bilateral renal cell carcinoma lesions developed. Five years later at age 48 years mental confusion developed and brain MRI showed a cerebellar lesion; histological evaluation revealed cerebellar hemangioblastoma.

FamilyInfo: The proband (patient 265) has multiple family members who presented with VHL symptoms but were unconfirmed with the mutation, due to no DNA sample being available or due to death before diagnosis. The proband's son (patient 266) presented with a CNS hemangioblastoma at 19 and retinal angioma at 27. Their first brother (brother 1, patient 267) presented with a CNS hemangioblastoma at 36 and a retinal angioma at 46. Their nephew (son of brother 1, patient 267) presented with a retinal angioma at 16. Their second brother (brother 2, patient 268) had a CNS hemangioblastoma at 30, retinal angioma at 20, and renal cell carcinoma at 41.
