Ethical issues in human genome epidemiology: a case study based on the Japanese American Family Study in Seattle, Washington.

Recent completion of the draft sequence of the human genome has been greeted with both excitement and skepticism, and the potential of this accomplishment for advancing public health has been tempered by ethical concerns about the protection of human subjects. This commentary explores ethical issues arising in human genome epidemiology by using a case study approach based on the ongoing Japanese American Family Study at the University of Washington in Seattle (1994-2003). Ethical issues encountered in designing the study, collecting the data, and reporting the study results are considered. When developing studies, investigators must consider whether to restrict the study to specific racial or ethnic groups and whether community involvement is appropriate. Once the study design is in place, further ethical issues emerge, including obtaining informed consent for DNA banking and protecting the privacy and confidentiality of family members. Finally, investigators must carefully consider whether to report genotype results to study participants and whether pedigrees illustrating the results of the study will be published. Overall, the promise of genomics for improving public health must be pursued based on the fundamental ethical principles of respect for persons, beneficence, and justice.
