23andMe not only sells genetic testing but also uses customer data in its R&D activities and commercial partnerships. This raises questions about transparency and informed consent. Based on a online survey conducted in 2017–18, we examine attitudes of 368 customers of 23andMe toward the company's use of their data. Our findings point at divides in the context of customers' awareness of the two-sided business model of DTC genetics and their attitudes toward consent. While most of our respondents (68%) were aware (...) that 23andMe could store their data and use it for certain purposes without their consent, over 40% were not aware that using and sharing customer data was part of the business model. Views were also divided regarding what type of consent was most appropriate. We explore the implications of these divides for participatory research and for the importance of transparency and trust in commercially-driven scientific knowledge production. (shrink)

Direct-to-consumer (DTC) genetic tests (GT) enable consumers to access a wide range of GT, without involving a healthcare professional, promoting an increasing disassociation of genetics from the clinical context. This study explores, through semi-structured interviews, the experiences and attitudes of European clinical geneticists towards DTCGT. Our results indicate that the participants have limited experience of consultations with patients regarding such tests. The majority of participants stated that consumers purchased tests out of curiosity and sought a general interpretation of test results (...) by a healthcare professional. Most respondents were skeptical of the quality of tests, especially regarding their clinical utility. The participants supported the importance of medical supervision and genetic counseling in this context. Finally, most respondents considered it their duty to accept consultations concerning DTCGT results. However, due to concerns over limited time and potential downstream costs, some participants supported that a prioritization system based on guidelines would be necessary. (shrink)
