Four distinct driver gene sets were identified for these four GBM individuals (ASS1, LRP1B and KIF4A for TCGA‐06‐0241; DCP1A, VWF, TBP, and CHEK2 for TCGA‐41‐2571; TP53, RB1, KIT, and LAMA3 for TCGA‐32‐2364; and PDGFRA, PARP1, DAB1, and CREBL2 for TCGA_19‐1390, Figs 4 and 5; Fig. S6). This evidence concerns the gene CHEK2 and glioblastoma.
