Huntington disease, one of the longest established and most serious human genetic disorders, has been the subject of considerable abuse during the present century in relation to the application of genetic knowledge, most notably in Nazi Germany but also in other countries. This disorder provides a valuable example of how abuses in the past need to be recognized and confronted, if we are to avoid their recurrence in relation to new molecular and computing techniques in genetics.
