NCI Definition: A tumor composed of two or more glial cell types (astrocytes, ependymal cells, and oligodendrocytes). [1]

Mixed gliomas most frequently harbor alterations in IDH1, TP53, ATRX, TERT, and NOTCH1 [2].

Most Commonly Altered Genes in Mixed Glioma

IDH1 Mutation, IDH1 Codon 132 Missense, IDH1 R132H, TP53 Mutation, and TP53 c.217-c.1178 Missense are the most common alterations in mixed glioma [2].
