Our Challenge To Find Your Cure

Vascular EDS Research

At Annabelle's Challenge, we are led by those affected by vascular Ehlers-Danlos Syndrome (vascular EDS) and work in partnership with the whole vascular EDS (vEDS) community. 

With over 500 genetically confirmed patients registered on our database we are uniquely placed to facilitate research and clinical trials into this rare genetic condition.

What we've done so far
  • Funded vEDS research projects and programmes. 
  • Funded the creation of one of the largest vascular EDS research databases in the world with EDS UK.
  • Facilitated and recruited patients for 10 research projects.
  • Work closely with the NHS EDS National Diagnostic Service.
  • Launched regional support groups and a vEDS steering group.
  • Hosted the world's first ever conference for vascular EDS patients and clinicians.
  • Stakeholders in the international VEDS Collaborative Group.
  • Supported vEDS Clinical Trials.
  • Supported MSc trainee Genetic Counsellors through Cardiff University. 
All research proposals are carefully considered with input from our board of trustees, vEDS steering group and professional advisory board.

New Paper Published!

A unique collaborative model providing supportive and self-advocacy tools to the rare disease community.


Juliette M. Harris, Jacqui Fish, Jared Griffin, Gemma Hasnaoui, Clare Stacey, Neeti Ghali, Fleur S. van Dijk.


This is a great example of collaborative work of the EDS Service, a highly specialised service commissioned by NHS England and Annabelle's Challenge Vascular EDS Charity including health care professionals, patients, carers and members of the emergency care project team.


The recommendations from this unique collaborative model include eight specific domains of self-advocacy: increasing knowledge of rare disease, taking care of mental well-being, taking care of physical well-being including routine care, the development of good working relationships between patients and health care professionals, information accessibility, emergency preparedness, taking part in education and outreach, and involvement in research and feedback opportunities.


Highlights

  • Having a rare disease presents a unique set of health care challenges.
  • Self-advocacy can help people with a rare disease get their needs met.
  • Empowering health care professionals in rare disease is important.
  • Specialised services are uniquely placed to help people with rare diseases.
  • Collaborations between patients and health care professionals support self-advocacy.

Research Update

Future needs for research into vascular EDS
  • Collect all sequence data from testing laboratories and facilitate contact with all individuals with pathological variants and those with variants of unknown significance (VUS) for follow-up.
  • Create animal models with common types of mutations - heterozygous substitutions for glycine in the triple helical domain and splice site mutations.
  • Develop clinical trials for small molecular intervention.
  • Develop models for genetic intervention.
  • Create an international web-based registry of individuals with vascular EDS with permission to contact and re-contact for both clinical information and involvement in clinical trials.

VEDS Steering Group

Working directly for the charity and the community we serve. 

The steering committee will help to shape the future of the charity as it continues to grow providing support, guidance, and overseeing the progress of all community based projects including events and research in the UK.

The team is made up of volunteers who are directly touched by vascular EDS including patients, parents and carers, they are also supported and advised by genetic counsellors from the EDS National Diagnostic Service in Sheffield and London.
