Abstract
The advent of gene panel testing is challenging the previous practice of using clinically defined cancer family syndromes to inform single-gene genetic screening. Individual and family cancer histories that would have previously indicated testing of a single gene or a small number of related genes are now, increasingly, leading to screening across gene panels that contain larger numbers of genes. We have applied a gene panel test that included four DNA mismatch repair (MMR) genes (MLH1, MSH2, MSH6 and PMS2) to an Australian population-based case-control-family study of breast cancer. Altogether, eight pathogenic variants in MMR genes were identified: six in 1421 case-families (0.4%, 4 MSH6 a..
