Incidental findings arise when clinically relevant genetic information about a research participant or patient is identified outside the scope of the original research objective or diagnostic test being performed. These findings can relate to carrier status for a heritable condition, misattributed paternity or increased susceptibility to a medical condition. The decision whether to disclose these findings to the research subject or patient is underpinned by many ethical, moral and potentially legal considerations. There is an urgent need for definitive guidelines for researchers and healthcare professionals. Major themes surrounding this issue include patient autonomy, patient welfare, harmful secrets and genetic literacy. The lack of relevant studies emphasises the urgent need for empirical investigations into the disclosure or nondisclosure of genetic incidental findings and the provision of guidelines to assist healthcare professionals and researchers.
Incidental findings are most likely to become more frequent due to advances in genome-wide technology and decreases in the cost of testing.
Patient and participant autonomy must be considered in any strategy designed to manage incidental findings.
Patient and participant welfare should be a driving factor in decisions regarding disclosure of incidental findings.
Genetic secrets can be harmful to both the patient/participant and the healthcare professional.
The genetic literacy of healthcare professionals and public alike need to be considered when discussing genome-wide testing technologies and attempts need to be made to increase knowledge across the board.
There is a lack of primary research data concerning patient and participant preferences regarding the management of incidental findings in research and the clinic.
Many clinician researchers have difficulty in separating their clinical and research obligations when genomic testing straddles the research–clinic interface.
There is an urgent need for coherent and ethical guidelines to address the management of incidental findings and assist researchers and clinicians in defining their legal, professional and ethical obligations.
