Of 246 patients affected with von Hippel-Lindau disease, 64 patients (26%) from 38 families had pheochromocytoma, including 33 newly diagnosed during screening studies and 31 treated before screening at NIH. Germline mutations in the VHL gene was determined from peripheral blood. Family 3948 and family 4589 were found with c.485G>T mutations in the VHL gene (legacy notation c.698G>t converted to NM_000551.3). Family 3948: 1/4 had pheochromocytoma, 1/4 had renal cell carcinoma, 4/4 had CNS hemangioblastoma, 2/4 had retinal angiomas and 2/4 had cysts. Family 4589: 2/2 had pheochromocytoma and 1/2 had retinal angiomas. Individual patient phenotype-genotype was not described in the paper.
