The original pathology diagnoses of lesions were the following: five astrocytoma IDH-mutant, two oligodendroglioma IDH-mutant and 1p/19q co-deleted, one pilocytic astrocytoma, one ganglioglioma, and two diffuse gliomas with morphological features consistent with astrocytoma grade 2, with IDH wild type. Here, IDH1 is linked to astrocytoma (excluding glioblastoma).
