Important insights have also been uncovered in the field of pediatric glioma, including the identification of recurrent mutation, fusion, and/or duplication events of the BRAF, FGFR1, MYB, and MYBL1 genes in pediatric low-grade gliomas, mutations affecting histone components (H3F3A p.K27M or p.G34) in pediatric high-grade gliomas, and aggressive subsets developing in midline central nervous system structures.
