Genetic Selection for Enhanced Health Characteristics

Abstract

This paper examines the UK regulatory framework and the ethical arguments surrounding the use of genetic tests, specifically considering how they would apply to selecting for enhanced health characteristics. It discusses the Human Genetic Commission reports on the use of genetic information more broadly, identifying the implied values and concerns arising from their conclusions. It argues that the HGC conflates the concepts of ‘best’ and ‘enhancement’ and this limits the persuasiveness of their moral stance against preimplantation genetic selection for nondisease characteristics. Subsequently, the paper develops a conceptual framework of ethical objections related to genetic tests and selection. In response, it is argued that there are good reasons to permit access to genetic tests (preimplantation and postnatal) on the basis that a) it will enable the accumulation of biocultural capital and b) the burden of proof deems prohibition to be unacceptable. In conclusion, a number of issues are described as unresolved, such as a lack of clarity over whether postnatal genetic tests should be considered medical interventions and the capacity of a national health care system to provide for enhancement choices. However, it is argued that neither of these factors creates insurmountable problems for the regulation of genetic tests for enhanced health characteristics.
