Introduction
The science of
genetics and genetic engineering has given rise to complex and problematic
ethical issues from its beginning.
Infamously, pseudo-scientific gobbledegook in the form of phrenology was
peddled in the nineteenth century to try and explain criminal behaviour. Even
more infamously, pseudo-scientists attempted in the early twentieth century to
use genetics to advance theories about racial differences.
In both cases the
theories offered were subsequently discredited fairly easily on scientific
grounds, without even needing to question the ethics or motivations of their
proponents. Far from removing the ethical questions with genetic technology,
however, just as many serious moral and ethical philosophical questions
continue to arise with legitimate scientific advancement.
One example is
that of genetic screening of embryos and people to detect potential diseases or
other conditions. On one episode of the BBC’s Moral Maze the question arose as to whether parents could or should
screen embryos before IVF treatment and what might follow from that. A representative of the deaf community opined
that if both parents were deaf, they might wish to choose the embryo that would
produce a deaf child, since they would be able to relate to the child better.
This runs counter to what I imagine would be most people’s instinctive reaction
– that an embryo should be chosen that would be the most ‘able-bodied’ to use a
contentious description. And yet the
argument from the deaf parents’ perspective was a cogent one: life for a deaf
person may be equally fulfilling and certainly is equally worthy of respect as
for someone who can hear, and therefore the parents should not be denied their
choice.
On the other
hand, suppose the parental choice is based on cultural norms that offend that
of the majority: some London hospitals ceased telling parents the sex of unborn
children because it was noticed that within some communities a disproportionate
number of children born were male, and on further investigation it was found
that abortions of female foetuses were commonplace. Here is a classic dilemma
for a multicultural society: given that abortion is legal, did the state have
the right to prevent parents from following a cultural preference for male
children? (In my view: yes).
The case
Another
question arose recently in the case of X
County Council v a mother and others [2013] EWHC 953 (Fam), [2013] All ER
(D) 231 (Apr). The case concerned two young boys (aged one and three) taken
into the care of a local authority, with the intention that they would be
adopted. The father, as well
as admitting violence in the home, said that both his mother and brother
suffered from Huntingdon’s disease (HD).
There was a chance therefore that the children had inherited the gene,
and the question arose as to whether they should be screened to confirm the
question either way.
Huntingdon’s
disease is a hereditary disorder of the central nervous system caused by a
defective gene on chromosome IV. The
faulty gene causes damage of the nerve cells and areas of the brain. Anyone whose parent has the disease is born
with a 50% chance of inheriting the gene.
Anyone who does inherit the gene will develop the disease at some
stage. The symptoms usually arise
between the ages of 30 and 50, though they may do so earlier. The extent of the symptoms varies from person
to person. In the later states of the
disease the physical and mental disabilities may become profound and, if so,
the sufferer will require extensive care and support.
The local
authority took the view that the children should be screened to see whether
they had the gene or not, and applied to the court accordingly. There was no dispute that the power of the court to order a medical or psychiatric examination or other assessment under ss
38(6) to (8) of the Children Act 1989 included screening for HD. It would of
course only make such an order if it thought it was in the interest of the
boys’ welfare.
The judgment
Baker J
considered evidence from the social worker concerning the prospects of
adoption; the evidence that there was that other members of the boys’ family
suffered from HD; and the expert evidence obtained by the parties about
HD.
He recorded the principal
arguments in favour of testing as follows. First, and most importantly, a
decision not to direct genetic testing would reduce the number of prospective
adopters for the boys - though it would not be
impossible. The guardian considered that it was possible to find adoptive
placements for both boys and that accorded with this court's experience. Many
children with profound disabilities were successfully adopted. Nevertheless, it
would be significantly more difficult to find adoptive placements and that was
a factor that pointed in favour of authorising the genetic testing.
Furthermore, his lordship felt that there was considerable force in the argument that matching
children with adopters who were fully informed about the children afforded the
best opportunity for a successful placement.
There were
other factors in favour of authorising testing. As a general rule, all children
had a right to be brought up with knowledge of their background and
inheritance. Unless and until testing was done, there would always be
uncertainty which would affect the children's carers and in due course the
children themselves.
On the other
hand, there were a number of cogent arguments against carrying out testing.
First, it was
the general practice not to provide genetic testing to children to determine
whether they had a condition whose onset occurred in mid-adult life where there
was no treatment which could be provided in childhood. It was generally
recognised that it was contrary to the interests of the patient for testing to
be carried out under the age of 18.
Secondly, it
was undesirable to treat children differently simply because they were being
considered for adoption. Save in exceptional circumstances, all other children
would be given the opportunity to decide for themselves when they were older
whether or not they should have the test. To order testing of the children in
the instant case at the present stage would deny them the right to make their
own decision when they were older.
Thirdly, though
difficult, finding an adoptive placement if there was an unresolved possibility
that the boys might carry the HD gene, would not be impossible.
Finally, when
children had been removed permanently from their birth family, it was
important, if possible, that they be placed permanently together. There was a
significantly greater risk that one boy will be found to carry the gene and the
other not. In those circumstances, there was, on the basis of the local
authority's plans, a significant prospect that the children would ultimately be
separated. That should be avoided if possible.
Baker J
therefore concluded that it was not in the welfare interests of the boys for
the court to order testing.
Comment
I have to say I
think the decision was correct. There was a real risk that the siblings might
be separated if one was found to carry the HD gene and the other not.
Moreover, as
Baker J said, screening would not normally be allowed for children living with
their birth parents. For reasons of
individual autonomy, it would be held that the children should be entitled to
decide from themselves once they became adult (or at least Gillick-competent)
whether they wished to be screened. That
right should not be denied children just because they happen to be on the list
for adoption. This, to my mind, is the
strongest argument, though Rosalind English on the UK Human Rights Blog disagrees. She argues:
Should more weight not have been
attached to the local authority’s case that, from a welfare perspective,
whatever the psychological consequences of testing, they were outweighed by the
likelihood that an unknown diagnosis will significantly decrease the chances of
a successful adoption? (…)
Of course there are adopters who cope
with children with profound disabilities and reduced life expectancy. But these
heroic people are much more likely to be found than to tip up by chance. It is
not sufficient – as the expert argued in this case – simply to educate
prospective adopters about the disorder and in particular how today’s research
is leading to the possibility of treatment in the future, without giving them
the opportunity to know whether this information is going to apply to their
immediate family situation; why else would they be interested? Had this case
not involved two children, with the potential for being separated as a result
of the discovery that one carried the gene and the other not, it is highly
likely that the court would have allowed the predictive testing to go ahead.
Nevertheless, I
still think it would have been wrong in the present case to undertake the
screening. Imagine if, in future, a complete disease/condition screen could be
done of all children. Would that not
render children waiting for adoption to be formed effectively into a queue,
with the least fortune genetic inheritors inevitably forced to the back? It seems to undermine the whole ethos of being
a parent if one’s attitude towards one’s children (adopted or natural) is
conditional upon that child’s genetic good fortune, though an interesting
question would arise if the authority knew that the children carried the HD
gene (or anything similar) and sought to withhold it from prospective
adopters.
But let no-one
assume that this is the last word on the case - still less the last time extremely difficult ethical questions will
arise more generally as a result of advancing genetic science.
