The pan-cancer prevalence of partner genes for FGFR1-4 REs is shown in Supplementary Table S1, available at https://doi.org/10.1016/j.esmoop.2022.100641; the most common partner gene for FGFR1-4 REs was TACC1 (71/279, 25.5%), BICC1 (288/1854, 15.5%), TACC3 (954/1158, 82.4%), and NSD1 (5/11, 45.5%), respectively. Here, BICC1 is linked to cancer.
