Abstract

We aimed to assess frequency and penetrance of BRCA1, BRCA2,and TP53 mutations in women diagnosed with breast cancer aged 30 years or younger, and then correlate this frequency with family history. 17 of 36 familial cases had a BRCA1, BRCA2, or TP53 mutation, compared with three of 63 non-familial cases. The calculated population frequency of TP53 mutations was one in 5000, substantially greater than previous estimates. This finding underlines the importance of accurate elucidation of a family history from young women diagnosed with breast cancer. Establishment of family history could help with development of patient-specific management and tumour surveillance protocols.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lalloo et al (2003, 2006) showed a predominance of BRCA1/2 mutations in familial aggregations of breast cancer, with penetrance estimates of breast cancer as high as 80-90% by 70 years of age.

    “Lalloo et al (2003, 2006) reported on the frequency and penetrance of BRCA1/2 and TP53 mutations in early-onset breast cancer in earlier papers. These papers showed a predominance of BRCA1/2 mutations in familial aggregations of breast cancer, with penetrance estimates of breast cancer as high as 80–90% by 70 years of age.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
