By comparison, elevated FGFR2, FGFR3, and FGFR4 gene expression levels demonstrated associations with worse outcomes for children with rhabdomyosarcoma tumors, but no significant associations with FGFR gene family member expression were identified for children with Ewing sarcoma [Figure 6E-L]. The gene discussed is FGFR4; the disease is rhabdomyosarcoma.
