Pediatric glioblastomas (GBM) including diffuse intrinsic pontine gliomas (DIPG) are devastating brain tumors with no effective therapy. Here, we investigated clinical and biological impacts of histone H3.3 mutations. Fo
[Paragraph-level] PMCID: PMC3422615 Section: ABSTRACT PassageIndex: 1
Evidence Type(s): Diagnostic, Prognostic, Oncogenic
Justification: Diagnostic: K27M-H3.3 mutation defines clinically and biologically distinct subgroups in DIPG, indicating its use in classifying the disease. Prognostic: K27M-H3.3 is universally associated with short survival in DIPG, while patients wild-type for H3.3 show improved survival, indicating its correlation with disease outcome. Oncogenic: The K27M-H3.3 mutation contributes to tumor development or progression in pediatric glioblastomas, as indicated by its prevalence in DIPG and association with specific copy number changes.
