Risks for other cancers remain unclear.  \nMethods Cancer associations for coding variants in ATM and CHEK2 were evaluated using whole-exome sequence data from UK Biobank linked to cancer registration data (348 488 participants), and analysed both as a retrospective case-control and a prospective cohort study. Odds ratios, hazard ratios, and combined relative risks (RRs) were estimated by cancer type and gene. Separate analyses were performed for proteintruncating variants (PTVs) and rare missense variants (rMSVs; allele frequency \u003C0 . 1%) .  \nResults PTVs in ATM were associated with increased risks of nine cancers at p\u003C0 .001 (pancreas, oesophagus, lung, melanoma, breast, ovary, prostate, bladder, lymphoid leukaemia (LL)), and three at p\u003C0.05 (colon, diffuse non-Hodgkin’s lymphoma (DNHL), rectosigmoid junction) . Carriers of rMSVs had increased risks of four cancers (p\u003C0 .05: stomach, pancreas, prostate, Hodgkin’s disease (HD)) . RRs were highest for breast, prostate, and any cancer where rMSVs lay in the FAT or PIK domains, and had a Combined Annotation Dependent Depletion score in the highest quintile.  \nPTVs in CHEK2 were associated with three cancersat p\u003C0 .001 (breast, prostate, HD) and six at p\u003C0 .05 (oesophagus, melanoma, ovary, kidney, DNHL, myeloid leukaemia) . Carriers of rMSVs had increased risks of  \nfive cancers (p\u003C0 .001: breast, prostate, LL; p\u003C0 .05: melanoma, multiple myeloma) .  \nConclusion PTVs in ATM and CHEK2 are associated with a wide range of cancers, with the highest RR for pancreatic cancer in ATM PTV carriers. These findings can inform genetic counselling of carriers.  \nINTRODUCTION  \nGene panel testing for cancer susceptibility is now an important part of clinical practice. To provide reliable genetic counselling, it is important to be able to provide risks for all cancer types. Many susceptibility genes, notably BRCA1, BRCA2, and themismatch repair genes, are associated with multiple types of cancer,1 2 but in general, cancer pleiotropy is poorly understood. Here we consider rare variants in two genes, Checkpoint Kinase 2 (CHEK2) and Ataxia-Telangiectasia Mutated (ATM), that are included on many cancer gene panels.
