Shared genetic data and the rights of involved people.

The authors examine the two main attitudes toward genetics: Exceptionalism and Undervaluation. They firstly pose the basis of the matter from the scientific point of view and then verify how these two attitudes really work in the different fields where human genetics finds relevant applications, dealing with the questions arising from the unique characteristics of genetic data that is shared among the whole bio-group. Then some judicial cases related to the conflicts arising when genetic data are stored in repositories, whatever the aims and reasons, are presented and discussed. The matter is then considered from the criminal law perspective, in the light of the new possible implications of DNA fingerprinting in criminal investigations. Finally, some general considerations on opposing Exceptionalism/Undervaluation viewpoints and the real reason for making up new rules are presented.
