Abstract

- Pheochromocytomas are neuroendocrine tumors of the adrenal glands that cause hypertension. More than a third of the cases are associated with hereditary mutations in a growing list of susceptibility genes, some of which are also somatically altered in sporadic pheochromocytomas. However, for the majority of sporadic pheochromocytomas, a genetic explanation is still lacking. Here we investigated the genomic landscape of sporadic pheochromocytomas with whole-exome sequencing of 16 paired tumor and normal DNA samples, and discovered on average 33 non-silent somatic mutations per tumor. One of the recurrently mutated genes was FGFR1, encoding the fibroblast growth factor receptor 1, which was recently revealed as an oncogene in pilocytic astrocytoma and childhood glioblastoma. Including a subsequent analysis of a larger cohort, activating FGFR1 mutations were detected in three of 80 sporadic pheochromocytomas (3.8%). Gene expression microarray profiling showed that these tumors clustered with NF1- RET- and HRAS-mutated pheochromocytomas, indicating activation of the MAPK and PI3K-AKT signal transduction pathways. The results advance our biological understanding of pheochromocytoma and suggest that somatic FGFR1 activation is an important event in a subset of these tumors.
