HEDGE (Hypermobile Ehlers-Danlos Genetic Evaluation) Study

HEDGE Study, the search for the genetic cause of hEDS

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


To find preventions and treatments for hEDS, we have to understand the cause. Genetic studies like this one provide a path towards that goal. — Joel Hirschhorn, MD, PhD


  • To be part of this study each candidate must first complete the EDS Global Registry.
  • They must meet the 2017 criteria for hypermobile EDS upon interview and examination by one of our participating physicians.
  • Individuals may allow a family member to complete the registry on their behalf.
If we are successful in identifying the underlying genes for hypermobile EDS, the opportunities for earlier diagnosis and more comprehensive treatment and care are virtually limitless. We are incredibly grateful to the generous donors who have made this possible. — Lara Bloom

Have a question?



  • 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 2019. Additional screenings may be scheduled at various clinics worldwide with carefully selected clinicians.

Understanding the genetic causes of hypermobile EDS is absolutely crucial to the EDS community. It will allow us to make unequivocal diagnoses. Understanding of the genetic pathways leading to hypermobile EDS will inform the search for rational therapies for this disorder, and hopefully, eventually, a cure. — Clair Francomano, MD
