Peripheral blood from unrelated patients with pheochromocytoma was tested for mutations of proto-oncogene RET, tumor suppressor gene VHL, succinate dehydrogenase subunit D (SDHD) gene, and the succinate dehydrogenase subunit B (SDHB) gene. Of 271 patients with nonsydromic pheochromocytoma and no family history of the disease, 30 mutations were found in VHL. Multiple pheochromocytomas were statistically more frequent among patients with mutations than among patients without mutations (21 of 66 vs. 5 of 205, P<0.001). The mutation R161P (c.482G>C) was detected in the patient, referred to in the paper by c.695G>C due to a difference in transcript sequence. This missense mutation was found in the VHL gene and one patient with pheochromocytoma.
