As for 1p/19q-codel, an essential criterion for oligodendroglioma, Kim et al. introduced the 1p/19qNET model trained on IDH-mutant gliomas, reporting AUCs of 0.930 in a discovery cohort and 0.837 (95% CI: 0.796–0.878) in TCGA validation [80]. The gene discussed is IDH1; the disease is oligodendroglioma.
