KIAA1549: BRAF Gene Fusion and FGFR1 Hotspot Mutations Are Prognostic Factors in Pilocytic Astrocytomas..     ///    "In summary, we confirmed the high frequency of KIAA1549:BRAF fusion in PAs and its association with a better outcome. "    ///    We assessed KIAA1549:BRAF fusion by fluorescence in situ hybridization and BRAF (exon 15) mutations by capillary sequencing.     ///    KIAA1549:BRAF fusion was identified in almost 60% of cases.
