How to Test Huntington's Disease

Doctors try to perform genetic linking mapping, to test for HD. Genetic linking mapping is the isolating of the gene that could possibly have HD on it. The chromosome would have C-A-G on it, repeated 3 time, if the person in question had HD. To look on the tip of chromosome 4, which is were the C-A-G would lay if the person had HD, doctors would use a genetic marker. Huntington's Disease can be in any organ of the body, but it is most commonly found in the brain.
