41 non-related patients with retinal angiomatosis presenting in the Benjamin Franklin University Eye Clinic between 1988 to 1999 Germany were evaluated for the presence of other VHL lesions. VHL disease was diagnosed clinically in 33 patients based on the presence of other severe VHL lesions (spinal hemangioblastoma 45% prevalence, cerebellar hemangioblastoma 42% prevalence, renal cysts 39% prevalence, pancreatic cyst 39% prevalence, renal carcinoma 18% prevalence, PCC 18% prevalence). VHL germline mutations were identified in 27 out of 29 VHL families screened with molecular genetics. This patient with VHL-related retinal angiomatosis was found to have germline nonsense (c.208G>T) mutaion in the VHL gene. 1 other affected relative was also evaluated. ACMG evidence codes: 'PP4' because the patients' phenotypes and family history are highly specific for a disease with single genetic etiology.
