As Huntington's disease is inherited dominantly, a child of a parent who has/had the disease has a 50% chance of inheriting the defective gene. Often the disease affects several generations. Genetic testing for HD became possible in 1993 when the first non-sex-linked dominant disease gene was found. person with the Huntington's gene has one good copy of the gene and one faulty copy of the gene. His/her child will inherit either the good copy or the faulty one. The child who inherits the good copy will not develop Huntington's disease, while the child who inherits the faulty copy will.
