In incidental PPGLs, HRAS (11.7%), FGFR1 (11%), and RET (9.2%) were the top 3 mutated genes, whereas HRAS (17.9%), VHL (9.2%), and NF-1 (8.7%) exhibited the highest rate of mutations in nonincidental PPGLs. In incidental pheochromocytomas, the most frequently mutated genes were RET (10.9%), HRAS (10.4%), and VHL (8.6%), while in incidental paragangliomas, FGFR1 (32.8%), HRAS (16.4%), and EPAS1 (9.8%) topped the list. The frequency of NF-1 mutations was significantly lower in incidental than nonincidental pheochromocytomas (4.1% vs 11%; P\u2005=\u20050.0042), while FGFR1 mutations were far more common in incidental than nonincidental paragangliomas (32.8% vs 15.3%; P\u2005=\u20050.0076).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>More than half of patients with incidental PPGLs had mutations in common susceptibility genes.
