DISCUSSION Genomics and health: ethical,
legal and social implications for developing countries Dr Chee Heng Leng The major ethical, legal, and social issues (ELSI)
issues that have arisen in the context of developments in genomics and health in
developed countries are also of relevance to developing countries. The
question before the World Health Organization (WHO) today is: what role can it
play vis-à-vis these issues? It must identify its priorities and the
responsibilities that it should undertake. Current major activities, applications, and work in
genetics and genomics are extensive. The scope of the debate covers areas like
genetic testing and screening for diagnosis, treatment and prevention; genetic
reproductive screening that may allow for selection whether on the basis of
disease, disability, disorder, or sex, or perhaps in the future, even trait
selection; genetic manipulation (both somatic and germ line), for treatment,
prevention, or enhancement; and finally, genetic databases and research which
results in the production of knowledge and the development of techniques which
could be used for reproductive selection, treatment of disease, diagnosis,
prevention, or enhancement. Justice and resource
allocation By far the most frequently raised issue pertains to
justice and resource allocation. Foremost among the many aspects here is the
relative position of genetics and genomics vs other health care needs: What is
the relevance of genomic advances to countries that cannot even afford to
provide existing vaccines and essential drugs? In many developing countries,
even basic health infrastructure is lacking, and much more could be done to
improve health status by providing clean water and sanitation and improving
nutrition, rather than providing access to genetics services, or channeling
resources toward genomic research. Posed in another way, the question
becomes: Why have such vast global resources, both private and public, been
channeled to genomic research, when the majority have no access to basic
amenities and health care? The answer to that question lies in the balance of
political and economic power, and in the historical development and
under-development of economies and societies. Still, it is a useful question to
keep in mind when we think about the issue of justice and resource allocation.
The overriding fear is that advances in genomic science will increase
inequities: the gap between developed and developing countries, and between the
haves and the have-nots. Much has been said of the 10:90 ratio: where only
10% of global health research is on the health problems of 90% of the
population. The challenge here to link genomics research to the burden of
disease in the developing world, and focus it on the major infectious diseases
still causing high mortalities in developing countries - for example, on
pathogen genomics of such disease vectors and agents. Imbalances in equity and access to genetic services
exist across countries and between developed and developing countries.
Within countries, inequities also exist among different social classes.
Also, access to genetic services - or the lack of it - in a society will affect
women differently from men. How can we prevent these gaps from widening?
Can something be done so that the results of genetics and genomic advances in
health benefit those most in need of them? Since equity and access depend primarily on social
structure and economic development, a long-term solution will have to deal with
changing social structures and economic power relations. Nevertheless, a minimum
objective should be to monitor equity and impact. This will give us an
indication of whether or not the new genetics will lead to increasing inequities
and access. It has also been repeatedly emphasised that there is a need to
encourage the participation of developing countries in genomic research. When
countries are unable to afford the infrastructure and investment, it has been
suggested that WHO help to build capacity on a regional basis. This will help
increase access, and regional networks could also be built. It is also suggested
that WHO could play an advocacy role in advancing genomic research for diseases
that constitute major health problems in poor countries. This is a role
that WHO is already playing in other areas. Finally, there is a need to improve the
distribution and access to basic genetic services in developing countries.
In many cases, this would also help to improve women's reproductive health
choices. The impact on gender equity, however, should be monitored, as there
could also be situations in which women's position will be affected
negatively. Ownership issues Closely related to the issue of social justice and
resource allocation are the ownership issues. These arise when
institutions or companies patent genetic material from research or genetic
databases. This controversy has been erupting in the context of a fierce battle
over the accessibility of HIV-AIDS drugs in developing countries who are unable
to afford the high prices of needed patented drugs. These issues have taken on
several facets, of which three are crucial. First, should living material be patentable? Living
material may be ESTs, SNPs, gene sequences, partial gene sequences, cell lines,
tissues, organs, microorganisms, plants, or animals. If one agrees to
patentability, there is a debate on which kind of patent is appropriate, and
whether broad patents covering everything should be allowed. Those who object to patenting argue that gene
sequences and such are discoveries of nature, and not inventions. The
basis for objecting to patents on DNA fragments and ESTs is that these are
relatively easy to find, and that they constitute tools, rather than an
inventive step. HUGO, for example, has opposed patents on ESTs and SNPs on
this basis. Some scientists oppose patents as a barrier to the free access to
knowledge, impeding research. On the other hand, those who argue for
patenting say that insofar as patents protect the rights of patent holders, they
encourage the sharing of knowledge. In the global spectrum, at one extreme are
countries whose patent offices grant patents from ESTs to transgenic
organisms. Although human beings have been deemed non-patentable, organs,
genes, and other parts of the human body may be patentable. The US Patent
and Trademark Office is of course the prime example. At the other extreme
are the countries where all parts of the human body, including DNA sequences,
genes and cell lines, are deemed non-patentable. Countries that tend
toward this end include France, Austria and the Czech Republic. Many other
countries have an intermediate position, generally allowing for the patenting of
DNA sequences, genes, and cell lines, but not of organs and
organisms. The Organization for African Unity (OAU) has
proposed a model law based on the Convention for Biodiversity, which it hopes
the World Trade Organization (WTO) will eventually adopt. It has also
asked that the Trade Related Aspects of Intellectual Property Rights (TRIPS)
Agreement incorporate a general ban on the patenting of living organisms and the
natural processes that produce these living organisms. The second way in which the ownership issue has
been framed is the challenge posed by indigenous people's organisations, who
argue that living materials such as plants that are sourced by drug companies
for useful substances have actually been identified and sometimes even cultured
by indigenous peoples for years. They are therefore the repositories of
indigenous people's knowledge and intellectual property. This has been recognised in the formation of a
Committee on Intellectual Property and Genetic Resources, Traditional Knowledge,
and Folklore to study access to genetic resources and benefit sharing. This
concept also forms the basis for the Common System on Access to Genetic
Resources, adopted by Bolivia, Columbia, Ecuador, Peru and Venezuela.
Under this system, contracts have to take into account the rights and interests
of the suppliers of genetic resources, their derivatives and related intangible
components. They must also guarantee the equitable sharing of benefits
deriving from the access to genetic resources. Furthermore, in Peru, there
is a system of optional registration of the collective knowledge of indigenous
people with respect to biological resources, access to which would be subject to
authorisation granted by the indigenous people themselves. Both the 'patent on
life' and the 'indigenous people's resources' issues challenge the existing
patent system. The ownership issue has also been framed in the 'flexibility' and
'benefit-sharing' approaches, which do not challenge the existing patent system
but work within it. The focus of the 'flexibility' approach is the
debate on how patents should be enforced. At the core of this debate is
the TRIPS Agreement, 1994, which has clauses allowing for 'parallel imports'
(imports of drugs from countries in which they are the cheapest), compulsory
licences, and exemptions in certain situations, such as in public health
emergencies. The Brazilian victory in the HIV-AIDS drug case is an example of
this. In this context, the European Union is now pressing the WTO to be
flexible and to take public health into consideration in TRIPS. The other approach is benefits sharing, which
pertains to the ethical conduct of research as well as the setting up of
databases. In order to avoid exploitation of indigenous populations and other
vulnerable groups, guidelines may specify, for example, that benefit sharing
agreements be drawn up before the research or data base is set up. What is WHO's role regarding this issue? Is it an
intermediary or advocacy role? It already has experience negotiating drug
prices, and in benefit sharing. Should it expand its role beyond
that? What is WHO's stand on the 'patents on life'
issue? Should it take a stand? If it is to promote the interests of
developing countries, should it support the OAU's model law? What is WHO's stand vis-à-vis the indigenous
people's resources issue? Should it promote the common system of the five
Latin American countries? How should it play a part in WIPO and WTO
discussions? Should it have a statement on the review of the TRIPS
Agreement, for example? Stigmatisation and
discrimination Stigmatisation could affect entire communities
found to carry a particular genetic disorder, or to individuals. It is
more likely to have a greater impact in societies with lower levels of science
education, and in particular social contexts; for example, women could be more
vulnerable in societies practising arranged marriages. The issue of genetic discrimination has arisen in
two contexts: in employment, and in insurance. Currently genetic testing
is rarely done at the workplace, but this may change with the advances in genome
mapping as the range of disease and disorders to be identified from genetic
testing increases. Discrimination in employment has happened in the
past. In the United States for example, Blacks who tested positive for
sickle cell anaemia were denied employment even if they were healthy and may
never develop the disease. Workers in countries with weak labour laws, and
weak or non-existent labour unions will be particularly vulnerable Discrimination in health insurance will have a wide
impact wherever health care financing is predominantly risk-rated
insurance. This has already occurred in the US, and in response,
some states have set up legislation prohibiting or restricting the use of
genetic tests in insurance. But even in the United Kingdom with the National
Health Service, people have been discriminated against for life insurance on the
basis of genetic testing. (It was recently reported that the UK government
endorsed a ban on genetic testing by insurance companies.) The issues of stigmatisation and discrimination
raise the corresponding issues of privacy and confidentiality. Who will
determine the principles, bases and limits of privacy and confidentiality when
handling an individual's genetic information? If the principles have been laid,
who will ensure that the principles are adhered to in practice? And how
will this be done? There is a need for international guidelines to
address issues related to genetic testing in employment and insurance. There is
already a lot of discussion (for example, by the European Group on Ethics,
Nuffield Council) on this. WHO has also issued the Proposed International
Guidelines on Ethical Issues in Medical Genetics and Genetic Services
(1998). Nonetheless, it need not stop at developing international
guidelines. It could also play an advocacy role vis-à-vis governments, and
help build the institutional capacity to address problems of discrimination that
arise. Informed consent The issue of informed consent follows closely from
our discussion of genetic discrimination and stigmatisation. The importance of
free and informed consent cannot be overstated whether it is in relation to
genetic testing, research or databases. The difficulty here lies in obtaining
genuinely free and informed consent in societies where there is no such
tradition, or among communities unfamiliar with western scientific practices.
The requirements and process of informed consent are different for testing in
clinical settings and for research. In testing for disorders, genetic counseling
could be very important, especially when preventive interventions or abortions
are not accessible. In research, special consideration will have to be
given to obtaining consent, avoiding manipulation or coercion of vulnerable
persons (for example of women in communities where men make decisions), ensuring
that the population adequately understands the research, etc. In addition to the consent from individual
participants, the need for community agreement - and the method of achieving
this - may have to be ascertained. People should also be informed about the
potential future uses of their genetic material. In the collection of databases, the appropriate
process for informed consent needs to be identified. For example, will it be an
opt-in or an opt-out consent procedure? Further, when studying databases or
genetic material in existing repositories, can genetic material be used for
purposes other than that for which informed consent was given in the first
place? What is WHO's role? Definitely, international
guidelines are required for the introduction of testing or screening programmes,
for the informed consent process in testing and screening, for research, and for
databases. The 1998 Proposed International Guidelines are an initiative in this
direction. Other organisations have also developed guidelines. Does
WHO need to develop its own guidelines? Or should it review existing
guidelines with a view to endorsing them? Sex selection Although sex selection is in a way a discrimination
issue, it is discussed separately here to give it particular prominence. Sex
selection is a reality in some developing countries where female infanticide and
foeticide are carried out. There is a real danger that prenatal genetic
screening will lead to an increase in this practice. Developing countries are more often than not
strongly patriarchal. Sex selection occurs in an entrenched culture of son
preference and women's subordination where having daughters is considered to be
an economical disadvantage. Still, state policies can worsen the situation in
the context of an existing cultural bias. In China for example, the
one-child policy has resulted in a distortion of the sex ratio in certain
geographical areas. Discrimination, stigmatisation and sex selection in
society occur in the context of entrenched values, interests, and cultural
beliefs and practices. Their eradication requires investment in long-term
strategies of economic and social development and educational and cultural
upliftment. What should WHO do to convince national governments to invest
seriously in these long-term strategies? Eugenics Eugenics, the science of improving the human
population through controlled breeding, encompasses the elimination of disease,
disorder, or undesirable traits, on the one hand, and genetic enhancement on the
other. It is pursued by nations through state policies and programmes. The Nazi
state in Germany in the mid-20th century, for example, used mass extermination.
Other state means are forced sterilisation, selective immigration policies, and
population control policies. Eugenics is a current danger in dictatorial and
authoritarian states. It was not too long ago that one particularly
technocratic and authoritarian state instituted incentives and disincentives for
eugenic purposes. With advances in genomics, eugenics becomes possible through
techniques of somatic genetic manipulation, and possibly in the future, even
germ-line manipulation. It has been argued that though state eugenic policies,
which inevitably involve coercion, are objectionable, eugenic decisions by
individual parents constitute a free and informed choice and therefore should
not meet with censure. This view is debatable given that most societies, in
particular developing countries, do not have structures supporting disabled
persons. Moreover, women's reproductive decision-making processes are
constrained and influenced by the social and economic environment, as well as by
current norms in medical practice, practices such as directive counseling, and
also by social pressure. Indeed, while preventing serious disabilities, it is
important to ensure that we respect diversity and reaffirm the tolerance of
difference. What is WHO's role in this? Could there be international guidelines
or even international conventions, addressing eugenic state policies and
practices? Guidelines already exist for somatic and germ-line
manipulation. Does WHO need to look into the relevance of these for
developing countries? Could there be guidelines for individual reproductive
decision-making that would safeguard men's and women's reproductive rights
while also guard against eugenic practices? Ideology and genetics The general ideological context is important to
understand how genetics can be misunderstood and give rise to incorrect
suppositions of the genetic basis of racial differences, notions of superior and
inferior genes, and of how genes determine traits and behaviour. The existence
of social classes and hierarchical relationships, the dominance of reductionist
science, an emphasis on rote learning rather than critical thinking in
educational systems, are examples of social structure and processes in society
that do not enable an individual to easily understand the complexities of the
interactions of genes, environment, and culture. It is important to raise the level and quality of
scientific education in general. Specifically, it is important to provide
adequate and accurate genetic information, knowledge and education. Such efforts
would aid in countering genetic deterministic ways of understanding the role of
genes, and of genetic tests and interventions. It would also counter 'gene
hype', or unrealistic expectations of the potential applications resulting from
the genomic revolution. WHO may have a role to play in identifying the
educational needs of international agencies, national governments including
policy makers, and health care professionals. At the national level, it could
possibly also advocate on this need, and provide the tools for identifying the
educational needs at the level of the public, community and schools. There is
also a role in capacity building for genetics education, and in developing and
disseminating appropriate genetic educational materials. Nevertheless, other
international bodies, such as UNESCO, might have genetic education initiatives;
efforts should be coordinated rather than to duplicated. WHO might concentrate,
for example, on the educational needs concerning the delivery of genetic
and medical services, or in medical and health education. The risks and hazards of
genomics In human genomics, there are risks to the
individual inherent in genetic therapy and manipulation. Germ-line intervention
constitutes a special srisk of irreversible changes to human beings. Is a
moratorium on germ-line intervention sufficient, or should there be a permanent
prohibition? How could a moratorium or prohibition be monitored?
There is also a danger of errant states using human genomics to develop
biological weapons for warfare. Non-human genomics faces threats from genetically
modified organisms and transgenic organisms, to the safety of the environment
and the ecosystem. There are also trends toward antibody resistance in
pathogens, a reduction in diversity, and an increasing reliance on and dominance
of transnational corporations. WHO can play a role in quality assurance in genetic
services, by providing benchmark or 'best practice' models. Is there a role for
WHO as well, to monitor risks and hazards and to disseminate the information? Is
there a need for international guidelines and declarations on risks and hazards,
providing for moratoriums or prohibitions, for example, and is there a role for
WHO in this? Conclusion The purpose of this paper is to raise questions to
stimulate discussion and debate. It would be most helpful to focus on what WHO's
role should be. As a global health organisation, how can it most effectively
play a leadership role in debates on the impact of genomic science on human
ethics and society? What direction should it forge that is consistent with its
mandate of 'health for all'? Does it need to play the role of convenor,
coordinator, and mediator? WHO will have to set its priorities and develop the
concrete ways in which it can intervene in the global processes to improve
health in developing countries and in the interest of equity in
health. This paper was presented at the Thai Health
Research Forum - WHO Multi-Regional Consultative Meeting on Genomics and Health,
23-25th July 2001, Sofitel Central Plaza Hotel, Bangkok, Thailand.
