Associated Genetic Biomarkers

Overview

NCI Definition: A WHO grade II tumor composed of a conspicuous mixture of two distinct neoplastic cell types morphologically resembling the tumor cells in oligodendroglioma and diffuse astrocytoma. (WHO) [1]

Oligoastrocytomas most frequently harbor alterations in IDH1, TP53, ATRX, TSC1, and TET2 [2].

Most Commonly Altered Genes in Oligoastrocytoma

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