Novel TLE4-NTRK2 fusion in a ganglioglioma identified by array-CGH and confirmed by NGS: Potential for a gene targeted therapy.

Abstract

Gangliogliomas are rare neoplasms of the central nervous system that mostly originate in the temporal lobe and are associated with seizures. Literature mentions that BRAF mutations are most commonly associated with gangliogliomas. We discuss a unique case of ganglioglioma originating in the posterior fossa that showed multiple losses and a unique interstitial deletion at 9q21 by an array-comparative genome hybridization (array-CGH). The deletion led to a novel molecular fusion (TLE4-NTRK2) which was confirmed by next generation sequencing and provides a potential for a gene-targeted therapy.
