Based on the survival analysis, 10 (UBA52 TSC2, CDK6, PTCH1, CTNNB1, PTK2, BTRC, MAPK8, SRSF2, and RAP1A) of the 11 key genes were closely related to the overall survival of patients with both glioblastoma multiforme (GBM) and low-grade glioma (LGG) (Figures 3(c)–3(m)). This evidence concerns the gene BTRC and low grade glioma.
