This report, the proceedings of a workshop “Assessing the security implications of genome editing technology” is published by the InterAcademy Partnership (IAP). IAP is the global network of more than 130 national academies of science, medicine and engineering, together with four regional networks of academies in Africa, the Americas, Asia and Europe. These academies work together to support the role of science in seeking solutions to the world’s most challenging problems. The workshop workshop was held in Herrenhausen, Germany, on 11-13 October 2017 organised by US National Academies of Science, Engineering and Medicine (NASEM), the European Academies Science Advisory Council (EASAC) and the German National Academy of Sciences Leopoldina, to review the latest advances in genome editing and their societal implications.
