Since the discovery of the HTT gene, genetic testing for the number of CAG repeats has been developed. However, there are serious ethical questions raised by the prospect of prenatal testing as well as the testing of minors. Develop an argument for why
minors should not be tested for HD unless they demonstrate juvenile HD symptoms.
What will be an ideal response?
minors should not be tested for HD because there is currently not cure or preventative for the disease. This will have a direct impact on their quality of life as they will have to live with the knowledge that they will develop HD. In addition, minors may be denied health coverage based on their genetic test results. This is a continuing ethical dilemma for genetic testing.
