[The Washington summit: orange light for genome editing?].

The summit organised in early December 2015 considered in depth the various issues (technical, scientific, societal and ethical) raised by the prospect of genome editing using the extremely effective CRISPR system. Germline editing (for therapeutic or "enhancement" purposes) was stated to be irresponsible under current conditions, but the possibility that this could be considered in the future was not excluded; a mechanism for monitoring progress and possibly revising recommendations was proposed.
