Huntington's disease is a rare genetic condition that weakens nerve cells in certain areas of the brain. The disease gets worse over time. It gradually affects a person's ability to walk, speak, and think.
Everyone has the HTT gene that plays a role in Huntington's disease, but people who get the disease have an "expanded" gene. This means that a certain segment of the gene is longer than normal. Everyone who has this expanded segment eventually gets Huntington's disease.
This condition is caused by a change (mutation) in the HTT gene. It is passed down through families (inherited).
