ATRX and astrocytoma (excluding glioblastoma): No IDH1, IDH2, TP53, ATRX, TERT promoter, CIC, or FUBP1 mutations were identified in any of the cases, suggesting that gangliogliomas are genetically distinct from the majority of diffuse lower-grade gliomas in adults (both astrocytomas and oligodendrogliomas) [4].
