Transformative Potential in Medicine and Beyond

Perhaps the mogt immediate promise of genome editing lies in it ability to o correct diseasea- causing mutations. Somatic gene editing, where changes are made to non-reproductive cells, does not affect future generations and is widely considered ethically permissible under approvate oversight. Clinical trials are alredy underway for conditions such as sicle cell disease and beta- thalconsiia, using CRISERT fetal globi.

While somatic editing offers treatent for the individual, germline editing - modififying sperm, eggs, or embryos - could d prevent genetic disorders from being passed to ofspring.
