Molecular Landscape of Pediatric Low-Grade Gliomas: Insights From RNA-NGS and Bioinformatic Analysis.

ABSTRACT: Pediatric low-grade gliomas (pLGG) are the most common group of childhood brain tumors. Genetic alterations in the RAS-RAF-mitogen-activated protein kinase (MAPK) pathway are the molecular drivers in the vast majority of pLGG. A large proportion of pediatric pLGG are characterized by the presence of fusion genes. An institutional molecular analysis together with an RNA-NGS study was performed to reveal LGG-associated molecular alterations. In our cohort of pLGG patients, molecular alterations were identified in 318 out of 342 cases (92.9%) through a combination of RT-PCR, Sanger sequencing, and NGS methodologies. Fusion events were independently called using three fusion callers: Archer Analysis 6.0 and/or 7.0, Arriba version 2.4, and STAR-Fusion 24. Among these, STAR-Fusion had the lowest
