Abstract

Pathogenic germline variants in the BAP1 tumor suppressor gene can cause a cancer syndrome called BAP1 tumor predisposition syndrome ( BAP1 ‐TPDS), which is characterized by predisposition to mesothelioma, melanoma, renal cell carcinoma, basal cell carcinoma, and other tumors. Other genes that may predispose to mesothelioma are CDKN2A and DNA repair genes. Asbestos exposure has often been reported in patients with malignant pleural mesothelioma (MPM) and germline variants in BAP1 , but this exposure has never been quantified. We aimed to search for germline variants in BAP1 among 25 new Italian probands with suspected BAP1 ‐TPDS, summarize the prevalence of these variants in 39 Italian patients with familial MPM and other tumors recruited over a 5‐year period, and compare cumulative asbestos exposure in 14 patients with MPM and pathogenic germline variants in BAP1 , CDKN2A , or DNA repair genes with that of 67 patients without germline variants in 94 cancer‐predisposing genes. We report here a new pathogenic germline variant in BAP1 : c.783 + 2 T > C. The prevalence of pathogenic germline variants in BAP1 was 7.7% among patients with familial MPM (3/39). Patients with pathogenic germline variants in BAP1 , CDKN2A , or DNA repair genes showed lower cumulative asbestos exposure than patients without germline variants in 94 cancer‐predisposing genes ( P = .00002). This suggests an interaction between genetic risk factors and asbestos in the development of mesothelioma.

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.
