One of the most fatal genetic diseases, Huntingtons causes a breakdown of nerve cells in the brain. Recent studies have suggested that head injuries and brain and heart health play a role in the disease. It is likely that more than one mutation is required before the disease is manifest, and a number of genes may each make a subtle contribution to a person's susceptibility to disease; genes may also affect how a person reacts to environmental factors.
