How the Disorder is Inherited

Huntington's Disease is a dominant trait. The disorder is not that common. Huntington's Disease is located on the 4th chromosome. This disorder most likely occurs between the ages 30-50.

Diagnostic Tests

Huntington's disease is inherited in an autosomal dominant pattern. This means that everyone who inherits the faulty gene will eventually get the disease. A parent with a mutation in the HD gene has a 50 percent chance of passing the disease to their children.

Treatments do not slow the progress of disease, but they can help make the patient more comfortable. Medications ease feelings of depression and anxiety, others control involuntary movements. Physical or speech therapy helps Huntington's Disease patients lead more normal lives.
