After identifying 371 prognostic genes and 606 immune infiltration‐related genes, we identified 15 immune infiltration‐related genes closely associated with glioma patient survival, which were TNFAIP3, IL11, IDO1, TRAF3IP3, IL1R1, PIK3CD, PTGES, ICOSLG, IL17RA, CADM1, SLC2A5, CCL19, TPSAB1, IL21R, and ADAT2 genes, mainly engaging in the positive regulation of cytokine production, the positive regulation of immune response, and cell activation (Figure S1C, Supporting Information). This evidence concerns the gene PIK3CD and central nervous system cancer.
