Abstract [en]

Purpose Pheochromocytomas (PCCs) are rare endocrine tumors originating from the adrenal medulla. These tumors display a highly heterogeneous mutation profile, and a substantial part of the causative genetic events remains to be explained. Recent studies have reported presence of the activating BRAF V600E mutation in PCC, suggesting a role for BRAF activation in tumor development. This study sought to further investigate the occurrence of the BRAF V600E mutation in these tumors. Methods A cohort of 110 PCCs was screened for the BRAF V600E mutation using direct Sanger sequencing. Results All cases investigated displayed wild-type sequences at nucleotide 1799 in the BRAF gene. Conclusions Taken together with all previously screened tumors up to date, only 1 BRAF V600E mutation has been found among 361 PCCs. These findings imply that the BRAF V600E mutation is a rare event in pheochromocytoma.
