Juvenile onset Huntington's disease Global Registry

JOIN-HD, the Juvenile onset Huntington's disease Global Registry is managed by the Huntington’s Disease Youth Organization (HDYO).  JOIN-HD opened to enrollment for young people with JoHD and their families in February 2022.

The registry collects experiences from both young people who have JoHD and their caregivers. JOIN-HD will be carried out in 3 stages, with increasing information being collected at each stage. At stage 1, participant’s demographic data will be collected, along with information about any links they have with the HD community. At stage 2, information on both medical history and caregiver and patient experiences of JoHD will be collected. Stage 3 will incorporate a clinician-led interview and taking of family history. The information people add to the registry will help us understand more about JoHD.  

Goals of the Registry  

  • Identify and engage people with JoHD in the collection of information that will speed up research into this disease. 
  • Improve advocacy, care, and support for young people with JoHD and their families.  
  • Contribute towards creating a multinational network of leading healthcare JoHD professionals.  
  • Learn what people with JoHD and their families need so we can improve support and education programs.  

What Happens After Someone Registers?  

After participants express their interest in taking part, the registry coordinator will hold one-on-one screening calls with each of the families. Each participant will then receive login credentials to create an account on the JOIN-HD website and complete questionnaires, which at stage 1 include important demographic data and information on their links with the HD community. If the appropriate consents have been given, participants will be contacted with future research opportunities, including later stages of JOIN-HD when they become available.  

Later Stages  

Stages 2 and 3 of JOIN-HD will include additional questionnaires to gather more in-depth information about patient and caregiver experiences including medical history, life experiences, and family history. The required approvals will be obtained before these stages begin. Participants will receive new information sheets and be re-consented at each stage.
