Right Problem, Wrong Solution: A Pro-Choice Response to “Expressivist” Concerns about Preimplantation Genetic Diagnosis

In August 2005, the United Kingdom's Human Fertilisation & Embryology Authority launched a public consultation, seeking views on the use of preimplantation genetic diagnosis for the detection of cancer genes. The issue was considered by the Authority to be a possible source of particular controversy because it involved extending the range of conditions for which PGD can be licensed in a potentially important way: As well as testing for genes that would definitely cause disease traits, such as cystic fibrosis and muscular dystrophy, this would involve genes that would only possibly manifest themselves phenotypically. In other words, there is a very real chance that such an application of PGD would result in the destruction of perfectly healthy embryos.
