Huntington’s disease is a fatal brain disorder caused by inherited changes in a single gene. These changes lead to destruction of nerve cells in certain brain regions.
Scientists identified the gene in 1993. Anyone with a parent with Huntington’s has a 50 percent chance of inheriting the gene, and everyone who inherits it will eventually develop the disorder. In about 1 to 3 percent of cases, no history of the disease can be found in other family members.

Treatment of Huntington’s
-
There is currently no treatment for Huntington’s. Research is accelerating since scientists identified the gene involved.
