Should embryos with a hereditary disorder be transferred if no unaffected embryos are available?
Date:7/7/2008

ilability of some therapeutic options," said Dr Dondorp.

"In the case of PGD for hereditary cancer, room for manoeuvre will depend on a case-sensitive evaluation of aspects relevant to the 'high risk of serious harm' criterion, also in view of the family history. If this approach is acceptable and if further debate leads centres to decide that they would not categorically rule this out, pre-test information about centre policy should be adapted accordingly. It must be made clear that there may be, with conditions, room for shared decision-making about transferring affected embryos. But that does not amount to leaving it to the parents, as doctors cannot avoid their professional responsibility for the welfare of the future child."

He concluded: "However, professionals may still find it difficult to respond to such requests that lead not only to the deliberate conception of a child in need of special care, but also to the very outcome they set out to prevent when offering PGD to a couple. Is it acceptable to use PGD just for trying to have a better result than one is eventually prepared to accept? This fits in with a wider debate about the morally charged nature of PGD and the proportionality of its uses: is it acceptable to use PGD for avoiding treatable disease, such as MCAD, in the first place?"

Together with Professor Guido de Wert, also from Maastricht University, Dr Dondorp is writing a paper to be published in Europe's leading reproductive medicine journal, Human Reproduction, on these issues. This is the first time ethicists have considered the questions that arise as a result of extending the use of PGD to hereditary symptoms such as cancer and MCAD.
