In TCGA cohort patients with oligoastrocytoma, astrocytoma, oligodendroglioma as well as IDH wild or mutation, showed significantly different outcomes between low‐risk and high‐risk groups (Figure 7A–E), while in CGGA cohort patients just with oligoastrocytoma, astrocytoma, and IDH mutation showed significantly different outcomes. The gene discussed is IDH1; the disease is oligoastrocytoma.
