  1. aParticipant data for CAG repeat length, symbol digit modality test and total functional capacity score are taken from the most recent ENROLL-HD visit of the participant
  2. bThe HDProTriad questionnaire was developed for use in HD and measures motor function, cognition and emotion. Higher scores indicate a greater degree of impairment, and a score of one indicates normal function
