In addition, novel pathogenic mutations were detected in sporadic PPGL. PPGL with mutations in the hypoxia pathway had an earlier onset and higher norepinephrine level than those in the kinase pathway. Receptor tyrosine kinase (RTK; 22%, 24\/107), mitogen-activated protein kinase (MAPK; 14%, 15\/107), and tyrosine kinase (TK; 2%, 2\/107) pathways were the most frequently mutated pathways in PPGL.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our results provided the genetic mutation profile in PPGL tissues.
