Attitudes towards Genetic Information Delivered by High-Throughput Sequencing among Molecular Geneticists, Genetic Counselors, Medical Advisors and Students in France

High-throughput sequencing technologies performed in the clinical setting have the potential to reveal diverse genetic information. Whether it is initially targeted or unsolicited, strictly medical or not, or even information on a carrier status as part of preconception screening, access to genetic information needs to be managed. The aim of the current study was to gather potential attitudes of various stakeholders towards the sharing of genetic information from next-generation sequencing, and more specifically towards incidental findings, predictive findings, non-medical information and carrier status. Answers from a total number of 1631 individuals belonging to four different groups (45 molecular geneticists, 65 genetic counselors, 56 medical advisors to the state insurance plan, and 1465 university students) were collected through online questionnaires. Overall, the study reflects preferences towards the return of health risks related to serious diseases when effective treatment is available and information on reproductive risks. The importance of the perceived medical utility, both for disease prevention and treatment, was the main distinguishing feature. Attitudes from genetic health professionals were found more reluctant to receive a wide range of information. Hands-on experience with the practice of genetic testing is likely to influence perception of the utility of the genetic information that should be delivered. At the same time, perceptions of preconception genetic carrier screening brought out less differences between participants. Better understanding of the underlying interest in genomic information and thorough education on its value and usage are key elements to the adoption of future guidelines and policy that respect bioethical principles.
