Genetic test: Huntington's disease is due to an autosomal dominant mutation of the huntintin gene. The most definitive diagnosis of this disease is a positive test for this mutation. This genetic testing can be done before symptoms develop, but early diagnosis does not affect the outcome of the disease. Genetic counseling is recommended before testing.
