Breaching Confidentiality in Genetic and Non-Genetic Cases: Two Problematic Distinctions.

Ethical questions about confidentiality arise when patients refuse to inform relatives who are at risk of a genetic condition. Specifically, healthcare providers may struggle with the permissibility of breaching confidentiality to warn patients' at-risk relatives. In exploring this issue, several authors have converged around the idea that genetic cases differ from non-genetic cases (e.g., involving a threat of violence or the spread of an infectious disease) along two related dimensions: (1) In genetic cases, the risk of harm is already present in an at-risk third party, whereas in non-genetic cases, it is not; and (2) In genetic cases, the patient does not create a risk of harm to a third party, whereas in non-genetic cases, the patient does. I argue that these distinctions do not exclusively differentiate genetic from non-genetic cases and should not bear on the permissibility of breaching confidentiality. Instead, such determinations should be based on other considerations.
