CCND2 and primitive neuroectodermal tumor: PDGFRA amplification has been reported to be more common in diffuse hemispheric gliomas, H3 G34-mutant with glioblastoma-like histology versus tumors with primitive neuronal/neuroectodermal tumor-like features, while CCND2 amplification showed the opposite trend,6 but this was not seen in our cohort (Note S3).
