GroupInfo: In family E, 12 patients were diagnosed with VHL disease, and 3 patients passed away before this family was screened. The missense mutation p.V170D was found in this family. It is not specified in this paper which family members were genotyped and found to have this mutation.

GroupHPOFreeText: Overall, family E suffers from VHL clinical type 2B. Phenotypic information for each family member is described in detail in the paper (pages 557-558.) Briefly, Patient I-1 died of of renal cell carcinoma at age 55Y. Patients II-2 and II-4 died of obstructive hydrocephalus caused by a cerebellar haemangioblastoma at the ages of 33 and 39 years respectively. The proband (patient II-7), presented with obstructive hydrocephalus caused by a cerebellar hemangioblastoma, a secondary optic atrophy, no retinal angiomas at age 55. He also has pancreatic and adrenal cysts. His elder brother (patient II-3) has a small angioma on one optic disc, bilateral renal carcinomas, and cysts in cerebellum, adrenals and pancreas. His elder sister (patient II-5) has pale optic discs, an intra-medullary hemangioblastoma, unilateral renal carcinoma, bilateral phaeochromocytomas and a unilateral mamma carcinoma. Patient III-4, has a small parapapillary angioma and an ora serrata angioma with a dilated feeder artery and draining vein present in one eye. He also has cerebellar haemangioblastomas, bilateral phaeochromocytomas, renal carcinomas, pancreatic cysts, liver cysts and medullary haemangioblastomas. Patient III-6 has pale optic discs and suffers from a small cerebellar haemangioblastoma. Patient III-7 had bilateral phaeochromocytomas. Patient III-8 developed a very small angiomain one eye at the age of 28 years. She also has bilateral renal carcinomas. Patient III-10 has retinal angiomas in both eyes and also suffers from bilateral renal carcinomas and medullary haemangioblastomas. Patient III-11 suffers from a uni-lateral renal carcinoma. Patient III-12 has optic atrophy secondary to obstructive hydrocephalus because of a cerebellar haemangioblastoma and a macular retinal angioma that detached from the retina but is still attached to the optic disc. At age 27 new angiomas started to develop in both retinas including a recurrent angioma in the left macula with exudation in the posterior pole .She also suffered from a haemangioblastoma of the medulla oblongata and bilateral renal carcinomas. Patient III-13 developed retinal angiomas in one eye at the age of 32 years. Family member III-14 has pale optic discs with a normal neurological examination.
