NCI Definition: A primary or metastatic malignant neoplasm affecting the brain. [1]

Malignant brain neoplasms most frequently harbor alterations in TP53, NRAS, MTOR, FBXW7, and PTEN [2].

Most Commonly Altered Genes in Malignant Brain Neoplasm

TP53 c.217-c.1178 Missense, TP53 c.142-c.212 Missense, TP53 c.1-c.137 Missense, TP53 Mutation, and TP53 Missense are the most common alterations in malignant brain neoplasm [2].
