    1. Clinical BRCA1/2 reversion analysis identifies hotspot mutations and predicted neoantigens associated with therapy resistance

      [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.

    2. To assess this possibility, we first estimated, using the NetMHCpan-4.0 algorithm, how frequently in the general population neopeptides derived from the out-of-frame sequence following pathogenic mutations were predicted

      Evidence Type(s): Diagnostic, Oncogenic

      Justification: Diagnostic: The passage discusses common founder mutations such as BRCA2:c.5946delT and BRCA1:c.68_69delAG, indicating their association with neopeptides that are likely presented in the population, which relates to defining or classifying a disease. Oncogenic: The mention of pathogenic mutations and their associated neoantigens suggests that these variants contribute to tumor development or progression, as they are described as potential tumor antigens.

    3. Interestingly, we noted very few missense pathogenic mutations in the set of reported reversions. For example, in the Incidence tumour sequencing datasets used previously, we found that (40/849, 4.7%) of these pathogenic

      [Paragraph-level] PMCID: PMC7611203 Section: RESULTS PassageIndex: 16

      Evidence Type(s): Diagnostic, Oncogenic

      Justification: Diagnostic: The passage discusses the presence of pathogenic missense mutations, specifically mentioning the BRCA1:p.C61S and p.M1I mutations, in the context of their association with disease, indicating their role in defining or confirming a disease subtype. Oncogenic: The passage refers to the BRCA1:p.C61S and p.M1I mutations as pathogenic, suggesting that they contribute to tumor development or progression, which aligns with the definition of oncogenic variants.

    4. For each of these common founder mutations, we noted that the reversions that emerged in these patients were generally localised to the 3' flanking sequence of the original pathogenic mutation (transcriptionally downstre

    5. Amongst the 91 patients we collated data from, most (68/91, 75%) had unique pathogenic mutations (Figure 1E, annotated as "single-patient mutations" and Supplementary Figure 1). There were eight pathogenic mutations repr

      Evidence Type(s): Diagnostic, Oncogenic

      Justification: Diagnostic: The passage discusses the presence of specific pathogenic mutations in patients, indicating their association with disease, which supports the use of these variants for classification and diagnosis. Oncogenic: The mention of pathogenic mutations suggests that these variants contribute to tumor development or progression, particularly in the context of BRCA1 and BRCA2 mutations associated with cancer.
