Adam Nash is the first known case of a test-tube baby born to be a transplant donor thanks to a genetic test originally invented to check whether embryos carry an inherited disease. The American baby was born in Denver on August 26, 2000, to save his ailing six-year-old sister, Molly, who is suffering from an inherited, fatal blood disease, Fanconi anemia. The case has caused a furor in the medical profession, challenging medical ethics and sparking a debate as to whether the operation was acceptable, worrying yet inevitable, or a chilling step towards the “designer” infant.

The boy, who was born specifically so that his stem cells could replace the failing bone marrow of his sister, was selected among a batch of embryos, conceived in vitro, by his parents in the hope of finding a tissue match for their daughter. His parents said that, in any case, they wanted a second healthy child. They were previously reluctant to conceive, fearing that the same blood disease would affect any new baby. The selection, which took place at Chicago’s Reproductive Genetics Institute, used pre-implantation genetics diagnosis (PGD) in choosing an embryo free of the gene for Fanconi anemia. This technique is normally used to see if a fetus is carrying a serious genetic disorder such as cystic fibrosis, muscular dystrophy, hemophilia, or Huntington’s disease, a crippling disorder of the nervous system.

When Adam Nash’s tissue was found to be 100 percent compatible with that of his sister, he became the perfect donor. Molly’s doctors say she now has a 90 percent chance of survival due to a transplant of stem cells from Adam’s umbilical cord instead of the 30 percent she would have had with a transplant from a non-relative. The girl, who received the transplant in a Minneapolis hospital, is now recuperating from a painless procedure which involved the collection of cells from her brother’s umbilical cord and their infusion into her circulatory system. Her doctors are very optimistic that within a week they will be able to report a successful outcome.

The procedure has been both a promising and worrisome harbinger of where scientific advances are taking human reproduction in the near future. In some medical circles, it has won praise. However, in some others, it has unleashed furious accusations that Man is trying to play God – a charge that has colored so many past rows about reproduction, from contraception and abortion to in vitro fertilization itself.

The case, therefore, has raised questions about parents’ ability to choose the traits of their children for whatever practical or capricious reason they may have. Paul Vey, a consultant in stem-cell transplants at London’s Great Ormond Street Hospital, said that the issue raised questions about where the cut-off line should be in genetic screening. He also pointed out the fact that it was a start towards being able to choose the right color of eyes and the right intelligence of one’s children.

Vivienne Nathanson, head of Ethics and Policy at the British Medical Association, said regulations in Britain’s governing genetic screening were tighter than in the United States. She stated there was little doubt that British authorities would have agreed to the use of the technique to determine which embryos carried disease gene and would have avoided implanting those. She maintained that she was much less certain that they would have sanctioned the selection of the one healthy embryo that would have been the best tissue match.

Nicole Alby, a leading French child psychologist, argued that many would sympathize with the plight of the Nash family as they saw their daughter’s health decline and desperately sought a solution. She added that, in tragic cases of transplant or death, there was no easy solution. “It’s a very complicated problem in which no one has the right to make value judgments, a horrible situation for a family,” she contended.

Thierry Leblanc, a specialist in childhood blood disorders at Paris’ Saint Louis Hospital, said that the use of PGD to identify the donor had “reached the ethical limits.” However, he noted that there had been many cases in the past which were never reported by the media. He claimed that many desperate couples had attempted to have another child in the hope of providing a tissue match to save their children. Having no recourse to PGD, they used amniocentesis after 14 to 16 weeks’ pregnancy to see if the match was right. If it were wrong, the fetus was often aborted. Doctors, he asserted, did not advise any of these actions as a rule but could not prevent them altogether, thus, insinuating that desperate couples would take desperate measures in order to save their children.

In conclusion, some say that the Nash case marks a step towards the nightmare of “designer” babies selected for looks or smartness. Others defend it, saying a child’s life may be saved. Still, many others throw up their hands and say the issue is worrying yet insoluble.
