Case: M, 26Y0M, Chinese

DiseaseAssertion: VHL

FamilyInfo: The patient's sister (the proband) had the same germline mutation, and presented with a CNS hemangioblastoma at 24, renal cell carcinoma at 32, and multiple pancreatic cysts/tumors at 33. The proband's mother had a CNS hemangioblastoma at 35, however no genotyping information is available for her.

CasePresentingHPOs: HP:0010797; HP:0002666 (Hemangioblastoma, Pheochromocytoma)

CaseHPOFreeText: The patient presented with a CNS hemangioblastoma at age 20, and a pheochromocytoma at age 26.

Case: F, 27Y0M, Hungarian

DiseaseAssertion: VHL

FamilyInfo: The patient had an affected brother (IV-14) who carried the Ser80Asn mutation and presented with pheochromocytoma and retina hemangioblastoma. The patient's mother (III-7) carried the same mutation and had a brain hemangioblastoma and retina hemangioblastoma. The uncle (III-8) harboured the same mutation and had brain hemangioblastoma, pheochromocytoma, and retina hemangioblastoma. He had three kids, out of which only one carried the mutation but was asymptomatic (IV-16). The patient's grandmother (II-5) also harboured the same mutation and presented with renal cell carcinoma. This patient's great aunt (II-1) carried two different VHL mutations; the Ser80Asn and Pro25Leu but herself was asymptomatic. She passed the Ser80Asn mutation to her daughter, the proband (III-1), who had renal cell carcinoma, brain hemangioblastoma, and pheochromocytoma. Refer to figure 1 for pedigree.

CaseHPOFreeText: underwent surgery for multiple CNS hemangioblastomas at the age of 15, and at the same age multiple peripheral retinal hemangioblastomas were found in his right eye, which were treated successfully with laser photocoagulation and cryotherapy. At the age of 20, he developed a large peripheral retinal hemangioblastoma in his left eye, which was treated successfully with cryotherapy.
