FamilyInfo: The family history revealed VHL in his mother, who died at the age of 40, and in his maternal aunt and grandmother, deceased at 30 and 33 years, respectively. His mother was operated on three times for cerebellar hemangioblastomas, the first at 13 years of age. She had also been treated for bilateral retinal hemangioblastomas since the age of 19. In addition, she had surgery for a renal tumor at the age of 32 and also had pancreatic cysts. She died of the diffuse hemangioblastomas in the posterior fossa. Variant is stated to be previously identified in the family but it is not clear which members have been genetically tested.

CaseHPOFreeText: Referred at the age of 15 for decreased visual acuity of the right eye. Growth failure with short stature for age and lack of pubertal development was noted. This was confirmed by ophthal-mologic examination which also showed bitemporal quadranopsia. Two retinal vascular lesions had already been diagnosed and photocoagulated. Cerebral MRI examination visualized a voluminous pituitary adenoma (confirmed pathologically) with suprasellar extension compressing the optic fibres invading both cavernous sinuses. It also confirmed two small cerebellar hemangioblastomas. On follow-up, MRI showed a persistent pituitary adenoma (confirmed by pathology) with numerous mitoses. A cystic part of the main hemangioblastoma was also noted in the right cerebellum image.

GroupInfo: 3 members of this family were found to harbor the c.340G>C germline variant of the VHL gene. Members 1070 and 744 had unknown renal involvement. Member 742 presented with moderate renal disease (RCC). 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.

GroupPresentingHPOs: HP:0005584 (Renal cell carcinoma)

GroupHPOFreeText: Moderate renal disease (less than five solid lesions requiring surgical treatment, either unilateral or bilateral).
