In response to a commission by the Federal Government, the German Ethics Council has compiled an Opinion on the future of genetic diagnosis. On the basis of the right of people affected by a genetic test to know, their right not to know and their right of informational self-determination, the Council recommends in particular measures for the improvement of information, explanation and counselling. Other proposed requirements include special provisions on the conduct of prenatal genetic diagnosis, protection of those lacking the capacity to give consent, the quality of genetic tests and their funding within the healthcare system. The Council not only offers recommendations for political and legislative action, but also aspires to stimulate public debate on future developments in genetic diagnosis.
