Evidence Type(s): Prognostic, Oncogenic, Predictive

Justification: Prognostic: The presence of the K27M mutation in histone H3 is associated with worse overall survival in DIPG patients, as indicated by the significant difference in survival rates between patients with K27M mutations and those without. Oncogenic: The K27M-H3 mutation is found exclusively in high-grade astrocytomas and is associated with aggressive clinical behavior, suggesting its role in tumorigenesis. Predictive: The study indicates that histone mutation status, particularly K27M, is a significant predictor of overall survival, which may inform treatment decisions for DIPG patients.

[Paragraph-level] PMCID: PMC4159563 Section: RESULTS PassageIndex: 9

Evidence Type(s): Prognostic, Diagnostic, Oncogenic

Justification: Prognostic: The passage indicates that patients with the K27M mutation in histone H3 have worse overall survival compared to patients with no histone mutations, suggesting a correlation between the variant and disease outcome. Diagnostic: The K27M mutation is associated with specific tumor histologies and is used to classify patients into different groups based on their histone mutation status, indicating its role in defining disease subtypes. Oncogenic: The K27M mutation in histone H3 is described as contributing to tumor development, as it is found in a significant proportion of tumors and correlates with specific tumor characteristics.

[Paragraph-level] PMCID: PMC4159563 Section: RESULTS PassageIndex: 7

Evidence Type(s): Prognostic, Oncogenic

Justification: Prognostic: The passage discusses overall survival rates for patients with and without leptomeningeal spread, indicating that the presence of the K27M mutation correlates with worse survival outcomes. Oncogenic: The K27M variant is mentioned in the context of tumor spread and is associated with specific tumor types (GBM), suggesting its role in tumor development or progression.

[Paragraph-level] PMCID: PMC4159563 Section: ABSTRACT PassageIndex: 1

Evidence Type(s): Diagnostic, Oncogenic

Justification: Diagnostic: The K27M-H3 mutation is described as being exclusively found in tumors with specific WHO grade II-IV astrocytoma histology, indicating its role in classifying and defining the disease subtype. Oncogenic: The passage indicates that the K27M-H3 mutation is associated with tumors that behave clinically as high-grade astrocytomas, suggesting its contribution to tumor development or progression.
