PatientID: IP (Proband)

KindredID: C

Case: M, 35Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: Index patient presented with cerebellar hemangioblastoma, renal cysts, pancreatic cyst and bilateral renal cell carcinomas. Family members were not available for clinical and genetic screening except a brother whose screening revealed no abnormality.

CasePresentingHPOs: HP:0006880; HP:0005562; HP:0005584; HP:0001737 (Cerebellar hemangioblastoma, Multiple renal cysts, Renal cell carcinoma, Pancreatic cysts)

CaseHPOFreeText: Patient was operated for cerebellar hemangioblastoma at the age of 33 years. Preoperative clinical screening also showed renal cysts. Two years later, a pancreatic cyst and bilateral renal cell carcinomas were found and the patients underwent bilateral nephrectomy with subsequent chronic hemodialysis. Diagnosed with VHL Type 1.

VariantEvidence: A point mutation (c.712C>T) was found. Being that this variant is out of bound with respect to the NM_000551.3 reference sequence, it was concluded that this variant is noted in the Latif et al. (1993) reference and was translated to c.499C>T (NM_000551.3).

Case: F, 33Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The proband's brother had the same germline mutation, and presented with a CNS hemangioblastoma at 20, and a pheochromocytoma at 26. The proband's mother had a CNS hemangioblastoma at 35, however no genotyping information is available for her.
