Understanding Genetic Incidental Findings in Your Family (UNIFY Study)

To develop, prototype, and evaluate a novel procedure for offering probands' genetic results to family members. The intervention is to offer a deceased research participant's actionable germline genetic research finding, and depending upon the choice made by the next of kin, a disclosure of the research finding by a genetic counselor in a family conference call. Using mixed methods (quantitative and qualitative), the investigators will assess decision making, family communication, and actions and responses in individuals from families in which a proband is known to have a deleterious germline mutation in one of several known cancer susceptibility genes.
