The results showed that DKC1 expression and TMB were significantly positively correlated in 14 tumors including GBM, LGG, CESC, LAML, STES, SARC, LGG, STAD, PRAD, LUAD, HNSC, PAAD, OV, BRCA and BLCA, but negatively correlated in COAD, COADREAD and THCA (Fig. S5E). This evidence concerns the gene DKC1 and glioblastoma.
