Common Genetic Variation at <i>BARD1</i> Is Not Associated with Breast Cancer Risk in <i>BRCA1</i> or <i>BRCA2</i> Mutation Carriers

Interactors of BRCA1/2 have been implicated as modifiers of BRCA1/2-associated cancer risk. Our finding that BARD1 does not contribute to this risk modification may focus research on other genes that do modify BRCA1/2-associated cancer risk.
