Case: F, 32Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: Large multigenerational family with a history of both VHL and spinocerebellar ataxia type 2 (SCA2). Screening for clinical and genetic diagnostics were gathered as well as thorough information on non-living members. See family pedigree (Fig. 1).

CaseHPOFreeText: diagnosed with VHL in her early teenage years. She had retinal involvement beginning at the age of 13 treated by cryotherapy and laser therapy (presumably for retinal angiomas); and retinal detachment at the age of 23 requiring eye surgery. She had cysts of the pancreas and kidney detected at 22 years. She has also carried the diagnosis of OPCA since the age of 26-28 (new onset slurred speech and illegible handwriting). Patient had multiple renal cysts without renal tumours, however a large infiltrative enhancing mass in the tail of the pancreas was suggestive of a neuroendocrine/islet cell carcinoma, and liver metastatic foci

CaseProblemVariantFreeText: c.477del, p.Glu160Serfs10 should be used. Details: 477del same as 475delA bc that codon is AAA so doesn't matter which A gets deleted: there is an A at 475 476 477 so for HGVS we say that 477 (the latter) is deleted since that follows HGVS nomenclature. Thus use c.477del: p.Glu160Serfs10

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.
