Molecular Biology is revolutionizing medicine. There are a number of conditions, particularly exemplified by the @entity1162 , where there is no structural abnormality but where a subset of @entity1 is prone to @entity944 . The issues of appropriate care are very complex, because there is tremendous overlap between @entity1 with prolongation of the QT who remain asymptomatic and those with prolongation who are very symptomatic. Furthermore, even those who are prone to have one of the abnormal genes, may be asymptomatic. A large literature has developed, from both legal and ethical aspects, related to the fact that in @entity74 per se, not only is the @entity1 at risk, but so are many members of his or her family. A large literature has also developed as to which should be prime, the @entity1 's privacy or the responsibility to make sure the entire family is knowledgeable and perhaps tested. At the present moment our care is based upon the fact that the precise identification of the gene is not yet available on a routine basis. This of course, may soon change. But we will still have difficult decisions to make. Obviously, we have a responsibility as physicians to be as precise as our discipline allows, but we have a responsibility to be flexible. Relief of @entity148 , as an example, has to be a prime issue. This is certainly the case now when any information related to @entity1 with potential @entity944 is still incomplete. We must not approach the care of the @entity1 in such a way that protection of the physician may interfere with appropriate care. The discussion necessarily includes a variety of aspects.

Some legal, social, and ethical issues related to the genetic testing revolution, as exemplified in the XXXX .
