We used reverse transcription polymerase chain reaction for the 3 most common KIAA1549-BRAF fusions, together with BRAF V600E and histone H3.3 K27M analyses to identify relationships of these molecular characteristics with clinical features in a cohort of 32 PA patients.     ///    Pilocytic astrocytomas (PAs) are increasingly tested for KIAA1549-BRAF fusions.    ///     Pilocytic astrocytomas (PAs) are increasingly tested for KIAA1549-BRAF fusions.     ///    "Thus, in this small cohort, 15-9 KIAA1549-BRAF fusion was associated with midline PAs located outside of the cerebellum.
