The remaining six cases were: one ependymoma RELA fusion positive, one glioblastoma mesenchymal subtype, one diffuse midline glioma H3 K27M mutant, one pleomorphic xanthoastrocytoma/advanced stage ganglioglioma, one CNS high grade neuroepithelial tumor with BCOR alteration and one glioblastoma RTK II subtype (Table 1). This evidence concerns the gene RELA and glioblastoma.
