Figure 4. Types of FGFR alterations in pediatric sarcomas and neuroblastoma. Queries and resulting figures were generated in cBioPortal (http://www.cbioportal.org) by searching “sarcoma” and “neuroblastoma” separately and selecting all pediatric cancer studies and querying by FGFR1, FGFR2, FGFR3, and FGFR4, with the resulting OncoPrint for identified mutations, amplifications, and deletions shown for pediatric sarcomas[41,89-92] (A); and neuroblastoma[93-95] (B). FGFR: fibroblast growth factor receptor.
