The original histopathologic diagnoses comprised low-grade glioma (LGG) (n = 1), embryonal tumor NOS (n = 2), high-grade neuroepithelial tumor (HGNET) with PLAG1 fusion (n = 1), primitive neuroectodermal tumor (PNET) (n = 1), supratentorial ependymoma (n = 4), and oligodendroglioma (n = 1). Here, PLAG1 is linked to supratentorial ependymoma.
