Case: F, 16Y0M, Greek

DiseaseAssertion: Assumed VHL

FamilyInfo: The patient’s 50-year-old father has VHL consisting of retinal HBs diagnosed at the age of 20 years. He also has spinal cord HBs located in the neck. He was also found to carry the mutation NM_000551.3:c.433C>T that the patient carried. The patient’s 18-year-old brother and her 20-year-old sister are phenotypically healthy and repeated biochemical evaluation and imaging studies are negative. Her paternal uncle, aunt and cousins are also phenotypically healthy with no indications from either biochemical or imaging studies as they denied further evaluation. In addition, her paternal grandfather of unknown genotype died at the age of 85 years while her paternal grandmother is alive and has no problems, being 86 years old at time of writing.

CasePresentingHPOs: HP:0009713; HP:0006880; HP:0009711; HP:0001737 (Spinal hemangioblastoma, cerebellar hemangioblastoma, retinal hemangioblastoma, pancreatic cyst)

CaseHPOFreeText: The 16Y female patient first presented with back pain, headaches, numbness, dizziness, weakness and pain in the arms and the legs at 12Y. A hemangioblastoma in the thoracic spine and a hemangioblastoma in the neck were found. A year later, at the age of 13, multiple HBs in the right and smaller lesions in the left eye were found. Two asymptomatic cysts (2 cm and 0.8 cm) in the body of the pancreas were also found. During her recent evaluation, at the age of 16 years, MRI imaging revealed a large HB extending from the cerebellum to the Th8 vertebrae, with extensive solid and cystic nodules inside the mass and increased dimensions of the spinal cord.

VariantEvidence: It has been documented that dynamic organisation of pVHL–HIF1α recognition is focally centred on Gln145 within the L7 loop, and its tumourigenic mutant Q145H abolishes almost all of the correlated dynamic motions. In this report, Q145 is substituted by a stop codon, p.Q145X. This is a nonsense mutation resulting to a truncated VHL protein that lacks the last 68 amino acids and thus its function is abolished.

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
