JOIN-HD Registry is Now Open to Enrollment

We are THRILLED to announce that Stage 1 of JOIN-HD: the Juvenile onset Huntington's disease Global Registry is now open to enrollment for young people with JoHD and their families!

Participants self-enroll in this registry, and, at stage 1, no clinical information is collected.As a clinician, we invite you to inform your JoHD contacts of this registry. You will not enroll or refer patients, and therefore do not have to involve your local ethics or research review committees.  More details about this registry are below:


JOIN-HD is a global registry managed by the Huntington’s Disease Youth Organization (HDYO) that collects experiences from young people who have JoHD and their caregivers. JOIN-HD will be carried out in 3 stages, with increasing information collected at each stage. At stage 1, participants’ demographic data will be collected, along with information about their links with the HD community. At stage 2, information on 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 collecting 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 global 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 individuals 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 consent has 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.

What You Can Do 

The HD community is excited to participate, connect with each other globally, and provide information that will propel future research for JoHD patients. We need help connecting with as many families as possible to achieve our goals. If you have families who are or have been impacted by JoHD, please let them know about this registry and help them to understand the importance of participating.
