Abstract
Over the past decade, our understanding of the molecular drivers of pediatric low-grade glioma (PLGG) has expanded dramatically. These tumors are predominantly driven by RAS/MAPK pathway activating alterations (fusions and point mutations), most frequently in BRAF, FGFR1, and NF1. Furthermore, additional second hits in tumor suppressor genes (TP53, ATRX, CDKN2A) can portend more aggressive behaviour. Accordingly, comprehensive molecular profiling-specifically genetic sequencing, often plus copy number profiling-has become critical for guiding the diagnosis and management of PLGG. In this review, we discuss the most important genetic alterations that inform on classification and prognosis of PLGG, highlighting their diagnostic and therapeutic relevance.
期刊介绍：
The journal has been expanded to encompass all aspects of pediatric neurosciences concerning the developmental and acquired abnormalities of the nervous system and its coverings, functional disorders, epilepsy, spasticity, basic and clinical neuro-oncology, rehabilitation and trauma. Global pediatric neurosurgery is an additional field of interest that will be considered for publication in the journal.
