The objectives of human genome research are to construct genetic and physical genome maps, identify the function of specific DNA sequences, and in particular to determine the DNA sequence of active genes. Although not a unitary research endeavour, the sum of all the human genome research programmes worldwide is called the Human Genome Project. Another, much smaller project, called the Human Genome Diversity Project, specifically addresses genetic variation within and between populations.
Notable as an international collaboration led by scientists rather than their governments, the Human Genome Project (HGP) was first formalized by the USA in 1988 and commenced officially on 1st October 1990. Research goals, strategies and resources vary but the overall objective is to gain an understanding of the genetic basis of the species Homo sapiens. The DNA molecule is composed of four units, known as nucleotide bases and there are believed to be about three billion base pairs in the human genome. The first completely sequenced human genome is expected to comprise of both an X and a Y sex chromosome, which would formally make it male, and it will take about 10 more years to complete. Estimates of the overall cost vary between US$ 300-500 million.
Shadow of eugenics
Historically, the study of human genetics is associated with eugenics,
the science which deals with all the influences that improve the inborn
qualities of humankind. In the early part of this century genetic science
focused attention on the determination of the biological basis of traits
that were supposed to account for certain sorts of anti-social behaviour
and social degeneracy. However, there was a reaction to such eugenics-orientated
research, and anti-eugenicist scientists argued successfully for a human
genetics free of racial and class bias. However, the eugenics history of
human genetics casts a long shadow and there are those who argue that even
the contemporary emphasis of much human genome research is implicitly eugenic.
Big science in a small way
The HGP originated largely from initiatives taken in the mid-1980s
in the USA, notably by the molecular biologist Robert Sinsheimer, and Charles
DeLisi, director of the US Office of Health and Environment at the Department
of Energy (DOE). However, prominent US biomedical scientists insisted
that the National Institutes of Health (NIH) should take principal
control of the HGP rather than the DOE and were successful in persuading
the head of the NIH to support the genome project. By 1988 US-federally
sponsored research in the human genome had a budget of about US$ 88 million.
NIH-funded bodies received around two-thirds of the total, the DOE, the
remainder.
By 1988, Britain, France, Italy, West Germany, the Netherlands, Denmark
and the Soviet Union all had initiated some genome research and in that
year the European Commission proposed its own genome project: Preventive
Medicine: Human Genome Analysis. Initially rejected by the European
Parliament on the grounds that its preventive aims were unacceptably eugenic,
a revised proposal subsequently passed the European Parliament and was
adopted by the Council of Ministers. In 1989, the European Commission allocated
US$ 11.7 million to human genome research for the period 1989-90. A further
US$ 21.5 million was allocated for the period 1990-1994 and US$ 31.5 million
for the period 1994-1998.
Earlier, in 1987 the Japanese government, a late-comer to molecular
biology and human genome research, established its Human Frontiers Scientific
Programme, an international enterprise of cooperative basic research
into neurobiology and molecular biology. Total Japanese human genome research
funding from the Science and Technology Agency (STA) and Monbusho,
the Ministry of Education, Science, Sports and Culture, for 1995
is about US$ 35 million.
The knowledge produced by human genome research has great potential
to further the development of genetic screening tests for the identification
of carriers of genes implicated in genetic disorders, and to enhance the
techniques for DNA fingerprinting.
Genetic screening
Genetic screening encompasses a range of techniques used to diagnose
phenotypic traits which have or are believed to have a genetic basis. In
the West prenatal screening will usually provide information which allow
people to decide whether or not to have an abortion where fetuses are diagnosed
to be at risk of, for example, Down’s syndrome, spina bifida, Turner’s
syndrome, Tay-Sachs disease, sickle cell anaemia, or one of the thalassaemias.
However, in many developing countries abortion is illegal which reduces
the value of prenatal diagnosis of such disorders to the local population.
Besides the current debates on the desirability of this kind of information,
another drawback is most peoples’ lack of knowledge in understanding the
difference between being a carrier of a disease-related gene for a recessive
condition, in which the carrier usually has no symptoms, as opposed to
an affected individual who has two copies of such a gene. It is hard to
guarantee that the doctors who test individuals or populations provide
adequate genetic counselling when doctors themselves have minimal training
in genetics. Furthermore, in many countries the educational support, which
should accompany any routine carrier screening to allay any stigma which
may attach to the social status of individuals, is often inadequate and
carriers may suffer unfair discrimination and diminished status.
In medical ethics it is necessary to obtain informed consent before
a competent individual may be subjected to any medical procedure. Concerns
have been expressed about the lack of informed consent, not necessarily
because of researchers’ duplicity but because of difficulties of communication.
DNA fingerprinting
DNA fingerprinting is a technique which uses gene probes to generate
personal genetic profiles which are as specific to individuals as conventional
fingerprints and used to analyze evidence in criminal cases and paternity
disputes. In the USA the military is interested in using DNA identification
for all its personnel as an aid in, for example, the identification of
human remains. Employers, insurance firms, educational establishments,
the police, the law courts and immigration authorities all have a potential
interest in collecting the respective genetic profiles of potential employees,
policy holders, students, criminal suspects, paternity defendants and immigrants.
The proliferation of DNA data bases recording the genetic profiles
of individuals challenges the individual’s right of privacy. The majority
of countries do not have statutes that recognize the confidentiality of
public health information; and with regard to criminal justice systems
the lack of data security is a serious concern.
Human genetic diversity
The concept of the genome applies both to the genetic complement which
is unique to the individual as well as that which is unique to the species.
The genome of every individual is a version of the species genome which
is distinguishable from the genomes of other members of the same species,
the degree of similarity being an index of relatedness, with identical
twins having identical genomes. Genomic variation, both within and between
populations, is of great interest as a historical narrative of human activity.
The Human Genome Diversity Project (HGDP) specifically addresses
genetic variation, albeit in a form which by implication conceives of genetic
difference as being of more significance between races than within them.
Since many genetic disorders have a much higher incidence in particular
ethnic groups, sampling the DNA of these populations for such disorders
can aid the development of genetic screening tests, and ultimately the
development of a gene therapy. The HGDP, masterminded by Luigi Luca Cavelli-Sforza,
a population geneticist at US Stanford University, is supposed to
cost US$ 20 million, provided for by international donors.
The purpose of the HGDP is to collect large amounts of gene samples
from a world-wide selection of about 500 genetically distinct human populations.
Researchers have already collected genetic data from many peoples including
the San peoples of South Africa, Penans of Malaysia, the Australian Aborigines,
peoples from the Sahara, Latin American Indians, the Soamis of Northern
Norway and Sweden and the Hagahai people of Papua New Guinea.
Indigenous peoples possessing a valuable genetic diversity are yet
not valued because of themselves. Their value lies primarily in their extracted
genes. For example, health workers collected blood samples from twenty
four members of the Hagahai people and these were sent to the gene bank
of the US NIH. When seven people were found to have a particular virus,
HTLV-1 in their genetic make-up, a virus that was thought would help fight
leukaemia, in 1993 the US Department of Commerce applied for a patent
on the Hagahai peoples’ DNA sequence and its product.
It seems likely, therefore, that, in time, health products will be
developed which would not have been possible without the cooperation of
indigenous peoples, such as the Hagahai, but which they themselves cannot
possibly afford to purchase and from which they are unlikely to benefit.
Cognizant of the injustice of such outcomes a working group of Unesco’s
International
Bioethics Committee (IBC) recently criticized the HGDP and recommended
UN organizations not to endorse projects under this programme.

Bioinformatics and surveillance
To enable information gained from the HGP and the HGDP to be recorded
and made accessible, a new information technology has been developed, known
as bioinformatics, to computerize nucleic acid sequence information.
Human genome data are credited with providing information about the
past, present and future of individuals and species. Biometrical genetic
research is being conducted with the purpose of establishing correlations
between genetic constitutions and intelligence, anti-social behaviour,
mental illness, heritable diseases and workplace disorders.
Since genetic screening might be used to shift responsibility for work-related
diseases or unhealthy working conditions onto the workers, there has been
an increasing call for limiting discrimination based on genotype and the
imbalances which exist in all health systems throughout the world.
Patenting
Since the advent of recombinant DNA technology in the 1970s there has
been a major reinterpretation of patent law all over the world, so that
these days in some countries living organisms and their parts and processes,
including the cells and genes of humans, can be patented. Importantly,
the Dunkel Agreement negotiated in the General Agreement on Tariffs
and Trade (GATT) extended Western models of intellectual property rights
to developing countries.
In 1991 the NIH Office of Technology Transfer in conjunction
with NIH itself filed for patent applications on several hundred DNA fragments
isolated from brain tissue. These fragments known as complementary DNAs
(cDNAs) or ‘expressed sequence tags’ (ESTs), with unknown functions, list
Craig Venter and Mark Adams as the inventors. Many scientists, including
James Watson who was then the director of the NIH’s genome programme, objected
on principle to the patentability of such partial genetic information.
It is questionable as to whether or not such DNA sequences are ‘inventions’
at all or merely ‘products of nature’. It is also argued that such patenting
would impede the free flow of scientific information and therefore undermine
the informal and cooperative tradition of the HGP.
As a key critic in this debate, Watson was accused of not serving the
interest of America, rather reminiscent of the way Oppenheimer, the physicist,
was challenged before a US Security Board hearing in 1954 because
he was critical of further nuclear weapons developments in the USA. However,
Watson and the other critics of these patenting developments were supported
by many prestigious individuals, organizations and governments, for example,
the Human Genome Organisation and the American Society of Human
Genetics. In the event, the NIH 1991 patent application was rejected
by the Patent and Trademark Office (PTO) on all the three main patentability
grounds: non-obviousness, novelty, and utility.
In 1992 Venter resigned from the NIH to head the new Institute for
Genomic Research with a corporate partner, Human Genome Sciences
(HGS).
The corporation, owned by the venture capital firm, Health Care Investment
Corporation, retains the commercial rights to discoveries derived from
Venter’s research, although Venter has rights to publish. HGS has an agreement
which grants SmithKline Beecham (UK) rights to exploit many of HGS’s
discoveries; HGS receives substantial funding in return, and by the third
quarter of 1994 had been paid a total of US$ 100 million.
Researchers wishing to gain access to the HGS data bases are obliged
to agree to various terms and conditions pertaining to HGS’s rights to
file for patents for any technology arising from the use of HGS data. One
of Venter’s arguments for this constraint is that HGS uses much better
bioinformatics than the publicly-funded data bases. In the UK the Medical
Research Council actually prohibited any of its researchers to enter
into collaborative agreements with HGS. HGS has recently negotiated an
agreement with SmithKline Beechem, for free access to the sequence data.
| Human diversity prospecting?
On March 14, 1995 a US patent was issued to the National Institutes of Health (NIH) on a cell line containing the unmodified DNA of an indigenous man of the Hagahai people. The same patent application is pending in 19 other countries. The Hagahai number 260 persons living in the remote highlands of Papua New Guinea. They only came into consistent contact with the outside world in 1984. According to a press communique of the Rural Advancement Foundation International (RAFI), Canada/USA, due to the patent, one of the Hagahai men ceased to be the owner of his own genetic material. The patent has provoked anger in the Pacific and deep concerns worldwide. "This patent is another major step down the road to the commodification of life. In the days of colonialism, researchers went after indigenous people’s resources and studied their social organizations and customs. But now, in biocolonial times, they are going after the people themselves" says Pat Roy Mooney, executive director of RAFI. Mooney is investigating prospects to challenge the patenting of human genetic material at the International Court of Justice in The Hague, the Netherlands, as well as bringing the issue to the attention of the parties of the Biodiversity Convention and relevant multilateral bodies. RAFI has been closely following the patenting of indigenous people since 1993, when pressure from RAFI and the Guaymi General Congress led to the withdrawal of a patent application by the US Secretary of Commerce on a cell line from a Guaymi indigenous woman from Panama. The US Secretary of Commerce, Ron Brown, defends the patent by stating "Under our laws (...) subject matter relating to human cells is patentable and there is no provision for considerations relating to the source of the cells that may be subject of a patent application." Recent cases have demonstrated the potential economic value of human DNA from isolated populations in the diagnosis and treatment of diseases, and the development of vaccines. Blood samples from the asthmatic inhabitants of the remote South Atlantic island of Tristan da Cunha were sold by researchers to a California-based company, which in turn sold rights to its as yet unproved technologies for asthma treatment to the German company Boehringer Ingelheim, for US$ 70 million.

Conclusions
The HGP is double-faced: on the one side, it is providing new knowledge
of human molecular biology of importance for the development of diagnostic
tests for the presence of those genes which are implicated in diseases
and disorders, and for the development of gene therapies. However, on the
other side, genetic discrimination in employment, personal insurance, and
possible violations of individual privacy including the individual’s right
‘not to know’ about their genetic profile have become serious ethical issues.
We also share the concern of those who are critical of the potentially
exploitative aspects of the HGDP: in particular, the issues surrounding
informed consent, individual autonomy, the quality of genetic counselling,
and the injustice done when patented genes derive from indigenous peoples
who will clearly not benefit from such applications.
To address these concerns the National Center for Human Genome Research,
the NIH and DOE’s Human Genome Program have established the Joint
Working Group on Ethical, Legal, and Social Issues associated with
mapping and sequencing the human genome. UNESCO is preparing a ‘Declaration
on the Protection of the Human Genome’ and the Council of Europe
a draft ‘Convention for the Protection of Human Rights and the Dignity
of the Human Being with regard to the application of Biology and Medicine’.
We await with great interest the deliberations of these bodies on these
important issues.
