A couple have a child with Fanconi’s Anaemia. This is a severe genetic disorder which leads to early death. It can be cured by a bone marrow transplant from a suitable match.  Siblings commonly can provide that match.

The couple want to have a child and are undergoing IVF in order to make sure that an embryo will not have Fanconi’s Anaemia. As well as screening embryos to ensure they do not have the disease they can also choose an embryo that will be a suitable match for the existing embryo. Stem cells can be taken from the umbilical cord [which is usually discarded] of the new baby and used to cure the existing child.

Should they be able to select an embryo for this reason? What issues arise?
