Fluorescence in situ hybridization (FISH) analysis of 26 low-grade diffuse gliomas with BRAF gain additionally revealed BRAF-KIAA1549 fusion in one oligodendroglioma.     ///    Sequencing of cDNA in 17 low-grade diffuse gliomas showed BRAF-KIAA1549 fusion in another oligodendroglioma.     ///     Chromosomal 7q34 duplication and BRAF-KIAA1549 fusion is a characteristic genetic alteration in pilocytic astrocytomas.     ///    "These results suggest that low-grade diffuse gliomas with 1p/19q loss have frequent BRAF gains, and a small fraction of oligodendrogliomas may show BRAF-KIAA1549 fusion..
