Evidence Type(s): Oncogenic, Diagnostic, Prognostic

Justification: Oncogenic: The text indicates that KRAS mutations (p.G12D and p.G12V) and BRAF mutations (p.V600E and p.Q636X) are linked to brain AVMs, suggesting these variants contribute to disease development. Diagnostic: The detection of somatic mutations in AVM specimens indicates that these mutations can be used to identify the presence of the disease in patients. Prognostic: The observation that two patients with BRAF mutations presented at an older age than other participants suggests that these mutations may be associated with age-related disease characteristics.

[Paragraph-level] PMCID: PMC6938308 Section: ABSTRACT PassageIndex: 6

Evidence Type(s): Oncogenic, Diagnostic

Justification: Oncogenic: The passage discusses somatic mutations in KRAS and BRAF, indicating that these variants contribute to tumor development as they are detected in specimens from patients with AVM. Diagnostic: The presence of specific mutations (G12D, G12V, V600E, Q636X) is used to classify and confirm the mutation status of patients, which is relevant for understanding their disease.

Evidence Type(s): Diagnostic, Oncogenic

Justification: Diagnostic: The passage indicates that KRAS codon p.12G and BRAF codon p.600V somatic mutations have been linked to brain AVMs, suggesting their role in defining or classifying the disease. Oncogenic: The mention of likely somatic disease-causing mutations, including KRAS mutations (p.G12D and p.G12V) and BRAF mutations (p.V600E and p.Q636X), indicates that these variants contribute to tumor development or progression.
