FamilyInfo: Proband (patient 42) has four family members confirmed with the mutation, and two family members who passed away before diagnosis/ genetic confirmation of the mutation. Family members confirmed with the mutation include: the proband's daughter (patient 43) who had retinal angioma (age 17), renal cell carcinoma (21), multiple pancreatic cysts/tumors (18), and a pheochromocytoma (19). His son (patient 44) who was asymptomatic at the time of assessment. His niece 1 (patient 47) who had a retinal angioma and renal cell carcinoma (22). And his niece 2 (patient 28) who had a CNS hemangioblastoma (19) and a retinal angioma (18). Family members who passed away before diagnosis and were not genetically confirmed include: his sister (oatient 45) who had a CNS hemangioblastoma (22), and his brother (patient 46) who had a retinal angioma and renal cell carcinoma at 52.
