For example, one of the distinctive norms of basic genome research has been a commitment to broad data sharing. Now that communities and advocacy groups exert influence alongside funders and data producers as stakeholders in genomics research, new compromises and guidelines are being considered with respect to data sharing [E-5]. Recent research has shown that research participants and community members often approve of wide data sharing for research purposes, but concerns remain regarding commercial use, retention of donor/community choices about sharing and secondary uses, and potential loss of privacy [D-5; E-5; G-2]. Loss of privacy is a particular danger for genomic data, which is potentially identifiable given enough SNPs; and identifiability is especially problematic in the case of rare genetic traits [B-5; D-5; G-2]. Researchers have voiced additional concerns about data sharing, including the risks it poses to the assignment of credit for breakthrough discoveries, which is crucial for career advancement and future funding through grants or patent revenue [E-5]. On a broader scale, questions have emerged as to the feasibility, for current hypothesis-driven research, of applying the rapid data-sharing
