As presented in Additional file 7: Figure S7, DLGAP5 expression was synchronously positively associated with TMB in various tumors, e.g., GBM (P = 0.0042), LUAD (P = 7.3e−11), PRAD (P = 1.7e−21), UCEC (P = 0.00039), BRCA (P = 0.017), COAD (P = 1.1e−06), STAD (P = 1.9e−05), SKCM (P = 1.6e−06), KIRC (P = 0.0011), READ (P = 7e−04), LGG (P = 0.012), KICH (P = 3.7e−24), ACC (P = 6.1e−06), and PCPG (P = 0.00035). Here, DLGAP5 is linked to glioblastoma.
