What are the ethical and legal issues involved with gene testing?
What will be an ideal response?
Gene testing is a double-edged sword in terms of what will be done with the information gathered. One side of the argument is the desirability of testing a person for an untreatable, incurable disorder that the current medical field is unable to deal with. Would the person want his or her employer or health insurance provider to be aware of a situation like this? On the other side of the argument is that this knowledge could enable the person and the family to plan ahead. Also, if the disorder were treatable, timely knowledge could allow the person to seek treatment that may prevent further pain and suffering. However, even in such as case, there is uncertainty about how an insurance company might react to this information, especially if the treatment were expensive. Insurance companies often reject current treatments and therapies. How can society deal with this situation and still allow people the right to know what disorder they've inherited? What about the mental anguish associated with knowing that one has a life-threatening genetic disorder?
