In the Ma et al and Grobner et al pan-cancer genomic studies [10, 11], comprising 2670 paediatric tumour samples of 24 cancer types combined, FGFR amplification was identified in only two cases (0.075%), both involving FGFR1, in one rhabdomyosarcoma (RMS) and one OS sample. The gene discussed is FGFR1; the disease is cancer.
