CaseHPOFreeText: Admitted with complaints of headache and diplopia. MRI indicated the presence of multiple lesions in perivascular areas neighboring both adrenal glands. An iodine 123 metaiodobenzylguanidine (MIBG) scan revealed multiple focal areas of increased uptake near the adrenal glands. The diagnosis of bilateral pheochromocytoma was confirmed histologically and immunohistochemically. The patient remained asymptomatic with no laboratory or radiologic abnormalities for six years of follow-up. At the age of 16, the patient was referred to our clinic with a visual defect in the left eye. Ophthalmologic examination led to the diagnosis of bilateral retinal hemangiomas, and he underwent laser photocoagulation.

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.

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.
