The newly developing CRISPR technique allows scientists to cut out a detrimental gene and insert healthy DNA, thereby altering the genetic code of that individual cell. If this mutation occurs in a germ cell (gametes, sperm or egg), it would carry through to every cell in the body and descend in successive generations. The CRISPR technique has the potential to eliminate devastating genetic diseases such as Tay-Sachs, cystic fibrosis or Huntington’s disease, however, many in the scientific community oppose human germline modification on the basis of ethical consequences. Regardless of these concerns, it has already begun. China is leading in this research, where scientists began experimentation on a nonviable human embryo in 2015. The United States has not officially prohibited germline modification, although the NIH Recombinant DNA Advisory Committee explicitly states that it “will not at present entertain proposals for germ line alterations”. Do you think we should allow genetic modification of the germline in the US? Consider if you, your child or a family member carried a devastating genetic disease that could potentially be eliminated using CRISPR, does this change your answer? Should we be concerned with the possibility of building a eugenic society (think Gattaca)? What about designer babies?
