20 vHL families were retrospectively identified in SickKids Genetics and Cancer Genetics Program SHIRE genetics database, with data entered between 30 August 1984 and 8 August 2016. 6 members of family 17 tested positive for the c.496_506del germline variant of the VHL gene. The proband (ID 1), cousin (ID 8), and second cousin (ID 25) were asymptomatic at 3Y, 4Y and 9Y respectively. The mother (ID 4) presented with CNS hemangioblastoma (23 and 25Y), retinal angioma (22Y) and renal and pancreatic cyst or tumor (unspecified) (25Y). An aunt (ID 5) presented with retinal angioma (16Y). A first cousin once removed (ID 22) presented with CNS hemangioblastoma (36Y). 2 members were assumed to have the variant, due to personal and family history, but were not genetically confirmed (ID 20 and ID 11). A grandmother (ID 11) and great aunt (ID 20) both presented with CNS hemangioblastoma at 43Y and 40Y respectively. ID 11 also presented with pancreatic and renal cysts or tumors (unspecified) but the age of presentation was unknown.
