My larger concern is who is paying for us not making the genetic effort: afflicted individuals and the social costs of trying to give them at least an approximately normal life. Weighing any risk against that cost? I can't make a pursuasive argument that we shouldn't proceed. Or as John Donne quipped in 1623, "... any man's death diminishes me, because I am involved in mankind. And therefore never send to know for whom the bell tolls; it tolls for thee."
