Ethical and legal issues and the 'new genetics'

Although uniquely personal, the information from gene analyses impacts on parents, siblings, children and even entire ethnic groups. Doctors need to carefully balance the right of a patient to privacy against the wider family and society interests, consistent with ethical standards and their legal obligations. Doctors also need to be in a position to advise their patients of potential risks that may result from obtaining predictive genetic information, such as discrimination by third parties. While these issues are not new, they occur with new sharpness in the "new genetics", where clinicians have to be familiar not only with clinical significance, but also the ethical and legal implications of genetic analyses and information.
