It's important to consider the potential long run impact of this work. It may be 30 years or more before the impact of genetic manipulation in humans becomes apparent. This could cause very signifcant suffering to those effected. The manipulation techniques are not entirely understood, in the past organisms that have been manipulated have not had the outcomes that were hoped for or expected. In addition during this work it is possible that suffering and death may be inflicted on human infants. These dangers surely must weigh heavily on anyone considering this sort of work be undertaken.
