Facilitated Cascade Genetic Testing for Relatives of Individuals With BRCA1/2 Pathogenic Variants: A Randomized Controlled Trial.
PURPOSE Despite the potential for substantial public health impact of cascade genetic testing (CGT), few at-risk relatives complete testing. We compared facilitated CGT with standard of care. METHODS Probands with newly diagnosed BRCA1/2 germline pathogenic variants were cluster-randomized to a facilitated cascade te...
