Patients PLGG2 and PLGG13 had chiasmatic/hypothalamic pilocytic astrocytoma negative for BRAF alterations; PLGG3 had midline tumor with same histology, positive for BRAF‐KIAA1549; PLGG5 had PXA with BRAF V600E mutation which subsequently transformed to a high‐grade tumor months later and PLGG14 was not biopsied. This evidence concerns the gene BRAF and pleomorphic xanthoastrocytoma.
