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 4783 were found with a p.Leu128Phe mutation (legacy notation c.595C>T converted to NM_000551.3) in the VHL gene. Family 4783: 3/3 had pheochromocytoma, 1/3 had retinal angiomas and pancreatic neuroendocrine tumor was also found in the family (number of affected members with PNET was not described). Individual patient phenotype-genotype was not described in the paper.
