Huntington's disease is inherited.
The Hereditary Disease Foundation ( HDF ) aims to cure genetic disorders , notably Huntington 's disease , by supporting basic biomedical research . Huntington 's disease ( HD ) , also known as Huntington 's chorea , is an inherited disorder that results in death of brain cells . This means a child of an affected person typically has a 50 % chance of inheriting the disease . The genetic basis was discovered in 1993 by an international collaborative effort led by the Hereditary Disease Foundation .
