Given the aforementioned differences in H3.1- and H3.3-K27M tumours, we next compared their clinical characteristics. We did not find any significant difference in terms of sex ratio (Fig. 5a), but found an earlier onset

Evidence Type(s): Diagnostic, Prognostic, Oncogenic
Justification: Diagnostic: The passage discusses the association of H3.1-K27M tumors with clinical characteristics and outcomes, indicating its role in defining and classifying the disease. Prognostic: The variant K27M is correlated with overall survival outcomes, with H3.1 mutations showing a better prognosis compared to H3.3 mutations, independent of therapy. Oncogenic: The mention of H3.1-K27M tumors suggests that this somatic variant contributes to tumor development or progression, as it is associated with clinical characteristics and outcomes in cancer patients.
