Group Info: Retrospective analysis of a longitudinal cohort of 21 VHL germline mutation carriers and retinal haemangioblastomas. All patients were categorized in two genotypic categories: missense mutations and truncating mutations. From this family, two individual was suspected of VHL disease, but neither developed RH.

Case: F, 23Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: The patient had a family specific p.Arg64Pro mutation, and VHL disease had a heterogeneous presentation in the family. The patient’s father initially presented with bilateral pheochromocytomas and clear cell renal carcinoma, and the patient’s son underwent unilateral adrenalectomy for pheochromocytoma at the age of 7.

CasePresentingHPOs: HP:0002668 (Paraganglioma)

CaseHPOFreeText: The patient was asymptomatic and presented with a palpable mass on the left side of the neck during a routine check-up. Somatostatin receptor scintigraphy revealed a hotspot near the left carotid artery, which indicated a paraganglioma. The paraganglioma was 2.5cm in size, and histological examination of it post-resection confirmed it was a paraganglioma. The patient did not present with any later tumors, although the length of follow-up is not specified.

CaseHPOFreeText: No tumors were reported in this patient: it was stated that they present an additional rare disease: the patient is heterozygous for CLN5protein in the neuronal ceroid lipofuscinosis rare disease. It is thus hypothesized that the CLN5 mutation in this VHL patient offers a protective effect to prevent tumors.

DiseaseAssertion: pheochromocytoma

FamilyInfo: Family suggesting incomplete penetrance of a VHL gene germline mutation. Mutation (p.R64P) was found in a family with 6 patients total with three generations. The earliest patient described (I-1) presented with renal cell carcinoma (age at diagnosis 48 years), 1 of their 6 children (II-1) at age 59 had no typical VHL manifestations after annual clinical monitoring and suggest non-penetrance in the patient; the second of 6 children (II-3), then aged 51, had bilateral pheochromocytoma diagnosed age 14. Their only child (III-5) had a paraganglioma with an age of diagnosis of 29 years, and a renal cyst. Patient II-1 had 4 children - one (III-1; aged 40) who presented as a carrier with no typical VHL manifestations after annual clinical monitoring; and another 32 years old presenting with pheochromocytoma. (See Figure 2 for pedigree)

DiseaseAssertion: VHL

FamilyInfo: Not relevant - She was the first child of consanguineous parents. Her family history was notable for type 2 diabetes and dyslipidemia but no history of pheochromocytoma, paraganglioma, unexplained sudden death, or condition relevant to VHL. However, the family screening for VHL has not been performed.

CasePresentingHPOs: HP:0006748; HP:0000819; HP:0008200 (adrenal pheochromocytoma; Diabetes mellitus; hyperparathyroidism)

CaseHPOFreeText: First brought to clinic for newly diagnosed diabetes mellitus and severe arterial hypertension. As symptoms, the patient complained of headaches, palpitations, diaphoresis, and hot flashes since one month. She reported also asthenia and body weight loss of five kilograms in two weeks. Pheochromocytoma was confirmed. CT showed adrenal masses: Right measuring 35×55×70mm, and left measuring 24×27mm. She underwent a bilateral adrenalectomy in two steps. Pathological examination confirmed bilateral adrenal pheochromocytomas. 12 months post, follow up is clear.
