Human genetic research: emerging trends in ethics.

Genetic research has moved from Mendelian genetics to sequence maps to the study of natural human genetic variation at the level of the genome. This past decade of discovery has been accompanied by a shift in emphasis towards the ethical principles of reciprocity, mutuality, solidarity, citizenry and universality.

The case for strategic international alliances to harness nutritional genomics for public and personal health.

Nutrigenomics is the study of how constituents of the diet interact with genes, and their products, to alter phenotype and, conversely, how genes and their products metabolise these constituents into nutrients, antinutrients, and bioactive compounds. Results from molecular and genetic epidemiological studies indicate that dietary unbalance can alter gene-nutrient interactions in ways that increase the risk of developing chronic disease. The interplay of human genetic variation and environmental factors will make identifying causative genes and nutrients a formidable, but not intractable, challenge. We provide specific recommendations for how to best meet this challenge and discuss the need for new methodologies and the use of comprehensive analyses of nutrient-genotype interactions involving large and diverse populations. The objective of the present paper is to stimulate discourse and collaboration among nutrigenomic researchers and stakeholders, a process that will lead to an increase in global health and wellness by reducing health disparities in developed and developing countries.

How the role of computing is driving new genetics' public policy.

In this paper we will examine some ethical aspects of the role that computers and computing increasingly play in new genetics. Our claim is that there is no new genetics without computer science. Computer science is important for the new genetics on two levels: (1) from a theoretical perspective, and (2) from the point of view of geneticists practice. With respect to (1), the new genetics is fully impregnate with concepts that are basic for computer science. Regarding (2), recent developments in the Human Genome Project (HGP) have shown that computers shape the practices of molecular genetics; an important example is the Shotgun Method's contribution to accelerating the mapping of the human genome. A new challenge to the HGP is provided by the Open Source Philosophy (I computer science), which is another way computer technologies now influence the shaping of public policy debates involving genomics.

Nutrigenomics, individualism and public health.

Issues arising in connection with genes and nutrition policy include both nutrigenomics and nutrigenetics. Nutrigenomics considers the relationship between specifc nutrients or diet and gene expression and, it is envisaged, will facilitate prevention of diet-related common diseases. Nutrigenetics is concerned with the effects of individual genetic variation (single nucleotide polymorphisms) on response to diet, and in the longer term may lead to personalised dietary recommendations. It is important also to consider the surrounding context of other issues such as novel and functional foods in so far as they are related to genetic modification. Ethical issues fall into a number of categories: (1) why nutrigenomics? Will it have important public health benefits? (2) questions about research, e.g. concerning the acquisition of information about individual genetic variation; (3) questions about who has access to this information, and its possible misuse; (4) the applications of this information in terms of public health policy, and the negotiation of the potential tension between the interests of the individual in relation to, for example, prevention of conditions such as obesity and allergy; (5) the appropriate ethical approach to the issues, e.g. the moral difference, if any, between therapy and enhancement in relation to individualised diets; whether the 'technological fix' is always appropriate, especially in the wider context of the purported lack of public confidence in science, which has special resonance in the sphere of nutrition.

Telling the truth about genomics.

Issues about communication in genomics have moved out of the clinic and into the public arena. Scientists other than clinicians are confronted by calls for public engagement. Genomics gives rise to these demands partly because it inevitably raises the three basic questions of philosophy as outlined by Kant: What can I know? What ought I to do? What may I hope? Genomics on its own cannot answer these questions. In relation to what can be known, its answer is at best partial. Nor can the ought question be settled by science. In fact, science is criticized for reducing options while claiming to be neutral in the pursuit of knowledge. The answer to the ought question is crucially related to the hope question in so far as this deals with issues about the point of human life generally. The role of public engagement in relation to all these questions may have different objectives. It is argued that there is more of a place for it in relation to the hope question than is commonly recognized, and in particular with regard to the role of science, which could benefit from developing a service ideal in the sense found in discussions of professional ethics.
