Disclosure of genetic information to family members: a systematic review of normative documents

PurposeFindings from genomic sequencing can have important implications for patients and family members. Yet, when a patient does not consent to the disclosure of genetic information to relatives, it is unclear how health-care professionals (HCPs) should balance their responsibilities toward patients and their family members and whether breaches in confidentiality are warranted.MethodsWe conducted a systematic review of normative documents to understand how HCPs should discuss and facilitate family disclosure, and what should be done in cases where the patient does not consent to disclosure.ResultsWe analyzed 35 documents from advisory committees at the national, European, and international level. We identified discrepancies regarding the recommended role of HCPs in disclosure. While almost all normative documents supported the disclosure of genetic information without patient consent in limited conditions, the conditions for disclosure were often not well defined. Documents provided varying degrees of information regarding what actions HCPs must take in such situations.ConclusionOur findings present concerns regarding the ability of these normative documents to guide HCPs’ decision making around the disclosure of genetic information to family members. Clearer guidance outlining the responsibilities and acceptability of disclosure is necessary to facilitate disclosure of genetic information to family members.
