IDH3A and glioblastoma: Then we retrieved all available metadata and used isocitrate dehydrogenase (IDH) mutation status and tumor grade to align our cohort to the 2021 World Health Organization (WHO) Classification of Gliomas, which groups adult-type diffuse astrocytic tumors based on IDH mutation status, with only IDHwildtype tumors with either characteristic morphology or molecular features of glioblastoma being classified as "glioblastoma, IDHwildtype"3.
