Huntington's Disease

Huntington's Disease is an inherited disorder that causes a progressive breakdown of nerve cells in the brain. This disorder was found by George Huntington in 1872. HD (Huntington's Disease) is a single gene mutation which means it doesn't affect all genes.

Life Expectancy

Huntington's Disease has a major impact on a person's lifestyle. This disorder usually appears in someone's life in their 30's or 40's . Usually they will live 10 to 15 years after being diagnosed with Huntington's Disease. This genetic disorder is more common within ancestry of the European ethnic groups and less common in people of Japanese, African or Chinese descent.

Testing/How to Prevent this Disorder

There are multiple pre-genetic tests that can be performed to test if an individual has Huntington's Disease. Pre-genetic diagnostic tests can be preformed with Vitro Fertilization to make sure that any fertilized egg implanted doesn't carry the gene. Researchers haven't found a cure yet, but they have identified the gene that carries Huntington's Disease. This disorder is not yet prevented, but treatments help with controlling symptoms. If you have a family history with HD, then you can talk with a genetic counselor. Testing can be done, to identify if a parent will or will not carry the gene for Huntington's Disease.


There are many organizations to support Huntington's Disease. Such as Huntington's Disease Support of America (HDSA) which is a popular support group for this disorder and the link is below so you can learn about HD and maybe donate towards Huntington's Disease. Also some other organizations are Huntington's Disease Youth Organization (HDYO) and National Organization for Rare Disorders (NORD) which supports Huntington's Disease.
