According to the interquartile range, FGFR3 expression spread varied in several cancers more than others, for example, skin cutaneous melanoma (SKCM) had a wide spread while testicular germ cell tumors (TGCT) had a narrow spread, which may be on account of some cancer types including several subtypes and thus having more genetic diversity (Supplementary Figure 2A). The gene discussed is FGFR3; the disease is cutaneous melanoma.
