Increased knowledge of the gene–disease associations contributing to common cancer development raises the prospect of population stratification by genotype and other risk factors. Individual risk assessments could be used to target interventions such as screening, treatment and health education. Genotyping neonates, infants or young children as part of a systematic programme would improve coverage and uptake, and facilitate a screening package that maximises potential benefits and minimises harms including overdiagnosis. This paper explores the potential justifications and risks of genotyping children (...) for genetic variants associated with common cancer development within a personalised screening programme. It identifies the ethical and legal principles that might guide population genotyping where the predictive value of the testing is modest and associated risks might arise in the future, and considers the standards required by population screening programme validity measures . These are distinguished from the normative principles underpinning predictive genetic testing of children for adult-onset diseases—namely, to make best-interests judgements and to preserve autonomy. While the case for population-based genotyping of neonates or young children has not yet been made, the justifications for this approach are likely to become increasingly compelling. A modified evaluative and normative framework should be developed, capturing elements from individualistic and population-based approaches. This should emphasise proper communication and genuine parental consent or informed choice, while recognising the challenges associated with making unsolicited approaches to an asymptomatic group. Such a framework would be strengthened by complementary empirical research. (shrink)

Questions about information inform many debates in bioethics. One of the reasons for this is that at least some level of information is taken by many to be a prerequisite of valid consent. For others, autonomy in the widest sense presupposes information, because one cannot be in control of one’s life without at least some insight into what it could turn out to contain. Yet not everyone shares this view, and there is a debate about whether or not there is (...) a right to remain in ignorance of one’s medical, and especially genetic, information. It is notable, though, that this debate leaves unexamined the assumption that, if a person wants information, he is entitled to it. This paper examines the assumption, specifically in relation to genetics, where learning facts about oneself may reveal facts about other people, particularly one’s close relatives. This may be taken as a violation of their privacy, and since privacy is something that we normally think should be respected, it is worth asking whether one ought to abjure the opportunity to obtain genetic information for the sake of privacy. In effect, there may be an argument to be made not just for a right to remain in ignorance, but for a duty to do so. (shrink)
