TL;DR: The presence of H3F3A/ATRX-DAXX/TP53 mutations was strongly associated with alternative lengthening of telomeres and specific gene expression profiles, suggesting that defects of the chromatin architecture underlie paediatric and young adult GBM pathogenesis.

TL;DR: It is demonstrated that each H3F3A mutation defines an epigenetic subgroup of GBM with a distinct global methylation pattern, and that they are mutually exclusive with IDH1 mutations, which characterize a third mutation-defined subgroup.

TL;DR: Similarity network fusion (SNF) applied to genome-wide DNA methylation and gene expression data across 763 primary samples identifies very homogeneous clusters of patients, supporting the presence of medulloblastoma subtypes.

TL;DR: Findings argue for H3.3-mutation testing at diagnosis, which should be rapidly integrated into the clinical decision-making algorithm, particularly in atypical DIPG, while patients wild-type for H2.3 show improved survival.

TL;DR: Somatic copy number aberrations (SCNAs) in 1,087 unique medulloblastomas are reported, including recurrent events targeting TGF-β signalling in Group 3, and NF-κB signalling in Groups 4, which suggest future avenues for rational, targeted therapy.
