Abstract
Genetics is a field in which ethical and social problems have been most pressing. Despite this, new tests often are introduced almost immediately after the isolation of a new gene. Considerations of whether a particular test should be introduced at all seem to have little effect on the development and introduction of new tests. This paper explores how this lack of social and ethical assessment can be understood. In order to do so, the sociohistorical context of clinical genetics and the way in which this practice came about will be analysed in this paper with respect to the Dutch service for clinical genetics. It will be argued that the fragmented way in which tasks and responsibility have become distributed within clinical genetics services has led to a situation in which actors seem to have no control over the introduction of genetic tests.
