NCI Definition: A benign glial-neuronal neoplasm. It is usually supratentorial, located, generally, in the cortex and occurs in children and young adults with a long-standing history of partial seizures. A histologic hallmark of this tumor is the 'specific glioneuronal element', characterized by columns, made up of bundles of axons, oriented perpendicularly to the cortical surface. (Adapted from WHO) [1]

Dysembryoplastic neuroepithelial tumors most frequently harbor alterations in FGFR1, CUX1, BRCA2, ZMYM2, and TRIM24 [2].

Most Commonly Altered Genes in Dysembryoplastic Neuroepithelial Tumor

FGFR1 Mutation, FGFR1 Exon 14 Mutation, ZMYM2-FGFR1 Fusion, TRIM24-FGFR1 Fusion, and TPR-FGFR1 Fusion are the most common alterations in dysembryoplastic neuroepithelial tumor [2].
