Evidence Type(s): Predisposing, Oncogenic, Prognostic

Justification: Predisposing: The text describes gliomas arising in patients with a heterozygous germline mutation in NF1, indicating a genetic predisposition to tumor development. Oncogenic: The presence of somatic mutations and inactivation of the wild-type NF1 allele, along with the mention of specific mutations like p.R1276* and c.4110 + 2 T > G, supports the role of these variants in tumorigenesis. Prognostic: Kaplan-Meier survival analysis indicates that patients with NF1-associated gliomas have inferior outcomes, suggesting that the genetic alterations may have prognostic implications for patient survival.

[Paragraph-level] PMCID: PMC9468105 Section: RESULTS PassageIndex: 14

Evidence Type(s): Diagnostic, Prognostic

Justification: Diagnostic: The passage discusses the association of the BRAF p.V600E mutation with pleomorphic xanthoastrocytoma, indicating its role in defining or classifying this specific tumor type. Prognostic: The Kaplan-Meier survival analysis mentioned in the passage indicates that patients with NF1-associated gliomas have inferior outcomes, suggesting a correlation between the presence of certain mutations and disease prognosis.

Evidence Type(s): Predisposing, Oncogenic

Justification: Predisposing: The passage describes a germline mutation (p.R1276*) associated with an autosomal dominant tumor predisposition syndrome, indicating inherited risk for developing gliomas. Oncogenic: The passage discusses the somatic inactivation of the remaining wild-type NF1 allele, which contributes to tumor development in gliomas, indicating that the variant plays a role in oncogenesis.
