This paper reviews the usefulness of bioethical instruments such as the informed consent principle to handle ethical and political challenges of clinical trials in genotyping and DNA-banking and discusses an informed request model as well as other contractual relations between research institutions, patients, and their families.

Genetic database initiatives have given rise to considerable debate about their potential harms and benefits. The question arises as to whether existing ethical frameworks are sufficient to mediate between the competing interests at stake. One approach is to strengthen mechanisms for obtaining informed consent and for protecting confidentiality. However, there is increasing interest in other ethical frameworks, involving solidarity — participation in research for the common good — and the sharing of the benefits of research.
