It is of interest to note that the KIAA1549-BRAF fusion was typically observed in a low-grade pediatric tumor with oligodendroglioma-like morphology with extensive superficial parenchymal and leptomeningeal involvement (these neoplasms are called disseminated oligodendroglioma-like leptomeningeal neoplasms, DOLN) [154]. This evidence concerns the gene KIAA1549 and oligodendroglioma.
