BRAF and low grade glioma: Among KIAA1549::BRAF fusion-positive low-grade glioma (LGG) diagnoses, EAS and SAS patients disproportionately harbored exon 15:09 breakpoints (FDR < 0.05), and AMR patients demonstrated rare breakpoints, which were associated with lesser degree of surgical resection and worse event-free survival (EFS) versus other breakpoints (hazard ratio (HR) = 4.6, P = .03).
