Overview

NCI Definition: A tumor of the brain or spinal cord showing astrocytic differentiation. It includes the following clinicopathological entities: pilocytic astrocytoma, diffuse astrocytoma, anaplastic astrocytoma, pleomorphic xanthoastrocytoma, and subependymal giant cell astrocytoma. [1]

Astrocytomas most frequently harbor alterations in TP53, IDH1, ATRX, EGFR, and CDKN2A [2].

Most Commonly Altered Genes in Astrocytoma

TP53 Mutation, IDH1 Mutation, IDH1 Codon 132 Missense, TP53 c.217-c.1178 Missense, and TP53 c.142-c.212 Missense are the most common alterations in astrocytoma [2].
