      [Paper-level Aggregated] PMCID: PMC7611203

      Evidence Type(s): Oncogenic, Predictive, Predisposing

      Justification: Oncogenic: The text discusses multiple pathogenic mutations, including BRCA1 and BRCA2 variants, which are known to be associated with an increased risk of breast and ovarian cancer, indicating their oncogenic potential. Predictive: The mention of neoantigens derived from pathogenic mutations being likely presented by HLA class I complexes suggests that these mutations can be used to predict immune responses, which is a predictive aspect in the context of cancer treatment. Predisposing: The identification of common founder mutations such as BRCA1:c.185delAG and BRCA2:c.6174delT indicates that these variants predispose individuals to developing certain cancers, thus classifying them as predisposing mutations.
