Next‐generation sequencing promotes identification of mutations in non‐ BRCA 1/2 genes in hereditary cancer families. The contribution of mutations in moderate penetrance genes to hereditary cancer risk is not well established. Here, we report a family with early onset breast and fallopian tube cancer that was identified as carrying germline mutations in BARD 1 and ATM genes. Loss of heterozygosity studies suggest a causative role of the BARD 1 mutation in the development of primary peritoneal cancer, but fail to confirm an association between germline ATM mutations and breast cancer development in this family. Complexities in interpreting implications of mutations in moderate‐risk cancer susceptibility genes are discussed.
