In LAML, the highest expression levels were associated with mostly undifferentiated states, whereas in LGG, elevated expression levels were found in oligodendrogliomas, astrocytomas, and in IDH1 mutated tumors, suggesting that ZNF213-AS1 is involved in modulating differentiation and proliferation of tumors (Supplemental Fig. S6B–E). Here, IDH1 is linked to astrocytoma (excluding glioblastoma).
