laid down by the Chicago-based American Medical Association.

Using this
technique, Zain will have an 80 per cent chance of a match being found,
compared to 20 per cent from a brother or sister conceived naturally.
But even as the Park Hospital and scientific circles remain enthusiastic,
pro-life campaigners are bitterly critical. Is the child to be created
a mere medical commodity produced to save its brother? Will this decision
pave the way for designer babies who will be produced for spare parts?
The technology is also controversial because it involves screening of
embryos, some of which will be discarded if they do not contain the right
genetic code-although unused embryos are discarded after virtually every
IVF cycle.
A spokesman for the campaign group Life said: "This case raises
serious questions as to how far we should allow science to go. Should
we allow a child to be manufactured in order to serve the medical needs
of an older brother?" He added that while the term 'designer baby'
is often overused, it is appropriate in this case. Zain Hashmi's condition-beta
thalassaemia major-is a serious genetic blood disorder, he stated, adding:
"We understand his parent's request to use technology in this way.
But there are other lives to consider: Zain's sibling, who will have to
live with the knowledge that he/she was created to supply bone marrow
and the extra embryos that will be created and discarded in the course
of IVF procedures."
Dismissing criticism that the designer babies will become commercial
products, HFEA said that the decision would not set a precedent and each
case would be considered individually. Such treatment will only be allowed
after full, detailed consideration by the authority and under very strict
controls, it added.
The Park Hospital has already received over a dozen calls from couples
unable to find matches from donor banks for children who are suffering
from life-threatening diseases.
Wanda Georgiades, spokesperson at the Park Hospital, said: "There
are 12 other couples who have expressed an interest because they cannot
get a match from the donor bank. At the moment the embyros have to be
flown to Chicago because we do not have the technical facilities here
but I am confident that soon we will have them." The cost of the
entire procedure for the Hashmis will run into £10,000 to £15,000.
"For IVF treatment and drugs alone the cost comes to about £2,500
but having to send the embryos to the USA for tests makes the whole treatment
more expensive," says Georgiades.
The couples that are lining up are at the beginning of the process with
no guarantee they will all proceed. She said: "The process that the
Hashmis went through included extensive medical and scientific consultation.
The couples hoping to follow the Hashmis would also go through consultation
and counselling on the implication of their decisions." However,
she is positive that once the required facilities are available in the
UK, the total cost will be reduced.
The Hashmi family has gone on a contract with The Mail on Sunday and
Trevor McDonald Show which might help them foot the high bills. But the
cost here would work out less than required in repeated blood transfusions
for Zain, and will also ensure him a healthy life if all goes well.
Dr Ajai Singh, a general medical practioner for 20 years in the UK,
has welcomed the move saying that screening of embryos will offer couples
a cure for children suffering from inherited diseases and also allow them
to have babies without certain medical problems.
The UK Thalassaemia Society too has welcomed the move as it gives couples
a choice, though they do not perceive the condition to be "life threatening".
"We have members who are in their 50s, are married and have children.
More and more people suffering from thalassaemia are living longer but
they never get cured. The new treatment will definitely cure the disease
and a patient will not have to take blood transfusions and go for iron
chelation four to five times a week for life," said Elaine Hadari,
spokesperson of the society.
But where will the medical fraternity draw the line between who should
and who should not be allowed to go for pre-implantation genetic diagnosis
(PGD) and designer babies? What kind of control will be implemented? As
Singh ponders, if the treatment gets a commercial go ahead, people will
go for designer babies where the choice will be: should we go for a blue-eyed,
blond baby boy or a green-eyed, red head baby girl? But, he adds, "Once
it is permitted and becomes less expensive, it can be exploited."
The Hashmis, however, are not the first couple to go for PGD. In the
UK, this technique has been used before, resulting in 20 bonny babies
who would otherwise have been at great risk of inheriting serious diseases.
But these cannot be called designer babies as they were not created to
save another life. Zain's case is a dramatic shift in the British attitude
which indicated concerns that a designer baby would be viewed as a commodity-not
a person in her or her own right.
This attitude found voice when the world's first designer baby, Adam
Nash was born in the USA. In an interview with BBC Online, Dr Vivienne
Nathanson, the head of ethics and policy, British Medical Association,
suggested that the technique should not be allowed under British law because
of the possibility of the child simply being seen as a medical product.
Two years ago, Lisa and Jack Nash had created Adam, who donated stem
cells from his umbilical cord to his older sister, Molly, to replace her
failing bone marrow. Molly was born with Fanconi anaemia, a genetic disorder
leading to failure of bone marrow production. When trying for the Nashs'
second child by IVF, doctors used PGD to select a healthy embryo that
did not carry the disease. Lisa Nash underwent four IVF cycles before
becoming pregnant and each time the embryos were screened to eliminate
those carrying the Fanconi anaemia gene. The doctors also selected an
embryo which would produce the tissue match necessary to offer Molly the
chance of a bone marrow transplant.
Zain's disorder is different, but it too puts limits on the life he
will lead. But even as steps for his cure begin, the debate on the ethics
of designer babies rages on.
