According to the Huntington’s Disease Society of America, Huntington’s Disease is an inherited brain disorder that results in the progressive loss of both mental facilities and physical control. The disease usually emerges when a person is between 30 and 50 years old and can gradually lead to death. There is no effective cure for the disease, but there are ways to relieve the symptoms.
In The Brain: Teaching Modules, program 12, “Huntington’s Disease,” watch as Dr. Nancy Wexler discusses her research on the demographics and causes of the disease. Look at the moral issues surrounding DNA testing to determine an individual’s risk of developing the disease.
Gene therapy, replacing defective genes with normal genes, is a technique researchers have investigated to treat diseases like Huntington’s. Consider the implications of gene therapy along with other types of genetic engineering using the DNA interactive. Discussion questions can be found here.
