Ehlers Danlos Syndrome National Diagnostic Service

The national Ehlers-Danlos syndrome diagnostic service is a specialist service for individuals and families who are suspected to have complex Ehlers-Danlos syndrome (EDS). 

Please note we are unable to accept referrals from GPs or private consultants. We can only accept referrals from NHS Consultants.  

The service focuses on diagnosing complex EDS. Sometimes, it may be more appropriate for an individual to see their local general clinical genetics team in the first instance who can refer on to us if there is a complex diagnostic question. When the main issues are managing the day-to-day aspects of EDS it can be more useful to be referred to other specialists such as rheumatologists, physiotherapists or paediatricians. 

What is Ehlers-Danlos Syndrome?
EDS is a group of inherited conditions which can have features in common. These may include joint hypermobility (increased range of movement), stretchy skin and tissue fragility.

The main types of EDS include classical, hypermobile, vascular and kyphoscoliotic.  In its mildest form, symptoms can be limited to hypermobile joints but in the more severe forms it can be disabling and even life-threatening. Making the diagnosis of EDS can be difficult and for this reason a specialist service is needed for the complex Ehlers-Danlos Syndrome.

Description of service

We aim to provide an excellent diagnostic service for adults and children with suspected complex EDS and we strive to incorporate new diagnostic techniques and developments in our practice.

When a referral is accepted, we will send you a letter and arrange a telephone call from a genetic counsellor to gather information before your clinic appointment and discuss your questions or concerns. If it is 6 weeks since your doctor referred you to our service and you have not heard from us, please contact the coordinator to check we received the referral.

At the appointment you will be asked to discuss your medical history and family history with the consultant and have a physical examination. You may be offered a test such as a genetic blood test or skin biopsy. Occasionally more than one family member is referred and we would normally see the whole family together.

After your detailed assessment with us, if you are diagnosed with EDS-hypermobile type, often the condition can be managed locally.  If you have one of the rare types of EDS your condition may need to be managed in a specialist service.

When the service started it was led by Professor FM Pope, Consultant in Connective Tissue Genetics, who now contributes to our service in an advisory role.

The two branches of the Ehlers Danlos Syndrome national diagnostic service are based at Northwick Park and St Mark’s Hospitals in Harrow in North West London and at Sheffield Northern General Hospital. Both services are for adults and children.

Where are clinics held?

Adult and children's outpatient clinics are held on Level 8 of St Mark's Hospital within the North West Thames Regional Genetics Service (Kennedy Galton Centre).

Information for GPs

We are not able to accept GP referrals. Where the primary concern is diagnosis, GPs can refer the patient to their local regional genetics service. The addresses of regional genetics services can be found on the website of the British Society for Genetic Medicine. If appropriate, the geneticist could then make an onward referral to the EDS Diagnostic Service.

Where there are management issues to be addressed, relating to the hypermobility spectrum, it is often more appropriate to refer to a rheumatologist with an interest in hypermobility, or paediatrician.

We are part of a network of clinicians across the UK interested in improving outcomes for patients with EDS, and are happy to assist patients and their doctors with recommendations for ongoing management.
