53 patients with a molecularly confirmed VHL mutation (by PCR through EDTA-anticoagulated blood) and a pancreatic neuroendocrine tumor (ICT) were collected from the German NET-Registry and the German VHL-registry. An additional 296 patients were stated in this paper with a VHL associated germline mutation, but without pancreatic neuroendocrine tumors. 1 patient was found to have the above mutation (c.393C>A). This was a VHL patient with an ICT (pancreatic neuroendocrine tumor) taken from the VHL-registry. Other clinical manifestations outside of a pancreatic neuroendocrine tumor are possible, but were not discussed. ACMG evidence codes: 'PP2' because they observe a missense variant in a gene where missense variants are a common mechanism of disease.

GroupInfo: 2 members of this family were found to harbor the c.393C>A germline variant of the VHL gene. Member 5114 had no renal involvement. Member 5112 presented with mild renal disease. Families were recruited from the French VHL Registry. Enrolment in the study required identification of the germline VHL mutation (currently 85% of the families included in the French VHL Registry) and available data regarding renal phenotype. A total of 126 families fulfilled these criteria.

A case report of a 49Yo woman presenting with a spinal hemangioblastoma was reported. Molecular analysis confirmed the presence of the above mutation, 393C>A (N131K). Upon further workup, retinal hemangioblastoma, renal cysts, and a carotid body paraganglioma were identified. Familial screening showed 3 family members with a clinical diagnosis of VHL, who had all passed away before testing could be conducted. Clinical manifestations in these members included: renal cell carcinoma, retinal hemangioblastoma, and CNS hemangioblastoma.

PatientID: III:2 (case)

KindredID: 1

Case: F, 49Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: VHL disease was diagnosed in her relatives - although no genetic testing was directly performed on them prior to death. 2/3 of her siblings and her father were affected. Her father had retinal hemangioblastoma at 30Y, CNS hemangioblastoma at 40Y and died at 41Y. Her older brother had kidney cancer and died at 48Y, and her sister had retinal hemangioblastoma at 13Y and CNS hemangioblastoma at 29Y. The case’s daughter tested negative and their other living sister.

CaseHPOFreeText: patient at retinal hemangioblastoma at 22Y. At 47Y she reported pains in her second and third finger of the right hand. She developed large carotid body paraganglioma at the common carotid artery bifurcation, (49Y) coexisting with a hemangioblastoma situated intramedullary in region C5/C6 (the right-sided dorsal part of the spinal cord) at 47Y). 1 year after the hemangioblastoma resection, the spinal symptoms receded and the carotid body paraganglioma still was asymptomatic. Motor issues and Babinski syndrome were also observed.

Eighteen VHL patients who underwent pancreatectomy for one or several endocrine tumors at Beaujon hospital from 1997 to 2008 were retrieved from the file of VHL patients. All patients had VHL germline mutations. Age is at the time of surgery. Patients #8 (male) was found with this germline VHL mutation (p.N131K (c.393C>A)) and pancreatic endocrine tumours. The last known age of the patient was 26Y. Other phenotypes and demographics were unknown. ACMG PP4
