Huntington's disease is an autosomal dominant genetic disorder in humans that causes progressive degeneration of certain brain tissues and eventual death. No cure or effective treatment for Huntington's disease exists at this time. Symptoms of the disease often do not appear until the affected person is 50-55 years of age. Blood relatives of Huntington's patients are encouraged to seek genetic counseling before attempting to have children of their own to determine the risk of passing the gene to their offspring. The allele [ H ] that causes Huntington's disease is completely dominant over a recessive allele [ h ] that codes for normal brain function.
