In this edition of Cancer Research, Park and colleagues describe a new mouse model featuring a single amino acid substitution in the coiled-coil motif of BRCA1. This change prevents BRCA1 from interacting with PALB2 (partner and localizer of BRCA2), causing rapid cancer onset and a loss of blood cells similar to Fanconi anemia.See related article by Park et al., p. 4172
