PatientID: IV-13

KindredID: 1

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.
