Secondary researchers' duties to return incidental findings and individual research results: a partial-entrustment account.

Existing attempts to explain why secondary researchers might have any obligation to return findings to the contributors of genetic samples falter because of the lack of any direct interaction between the secondary researchers and the contributors. The partial-entrustment account of these obligations defended here circumvents this problem by explaining how a chain of special responsibilities can be forged even in the absence of any direct interaction.Genet Med 2012:14(4):467-472.
