HEDGE (Hypermobile Ehlers-Danlos Genetic Evaluation) Study

HEDGE Study, the search for the genetic cause of hEDS

Recruitment is underway for the genetic study of 1000 individuals with hEDS.



  • Participants will be invited to the screening events based on their information in the EDS Global Registry.
  • After providing informed consent, accepted participants will have their blood drawn for whole genome sequencing. Family members will not be automatically included in the study, so each family member must individually go through the recruitment process.
  • Recruitment will continue through 2020. Additional screenings may be scheduled at various clinics worldwide with carefully selected clinicians.


There are no scheduled events currently.

When will new event dates be announced? 

Currently, we cannot provide new dates. As soon as new dates are confirmed we will follow up with participants and post all updates on our HEDGE webpage. We will be announcing new dates and locations for the HEDGE screenings later in the year. The HEDGE team will contact those already signed up to offer a new date and time where possible if screenings are rescheduled in the same or nearby locations.

Will you still do these locations?

We will do all we can to still get to as many locations, but many of these events were connected to other canceled things happening. We will announce as soon as we can where we are able to get to.

Is there another way that I can participate in HEDGE remotely?

No. The only way to participate in HEDGE is by attending a confirmed screening event.

Can my doctor do the screening and blood test and send it to you?

No. The only way to participate in HEDGE is by attending a confirmed screening event.

How do I cancel my travel tickets and hotel? 

Please contact your travel provider and the hotel directly regarding your booking. Please check with your own credit card company and insurance company on their specific cancellation policies, in regards to getting your travel refunded.

How will this impact the HEDGE study?

There is no long term expected impact on the HEDGE study. However, we will be updating the timelines for the different stages of the study.

If there are any further concerns or questions about HEDGE screening events please contact registry@ehlers-danlos.com
