Annabelle's Challenge is the leading charity for vascular Ehlers-Danlos syndrome in the UK.
At the heart of the charity is Annabelle, a brave girl from Bury who is the inspiration behind our challenge to raise awareness and support for patients and families touched by vascular EDS.
Our Challenge To Find Your Cure
Vascular EDS is a life threatening connective tissue disorder that affects all tissues, arteries and internal organs making them extremely fragile. Patients are at risk of sudden arterial or organ rupture. Vascular EDS (previously known as Ehlers-Danlos type IV) is a rare type of Ehlers-Danlos syndrome caused by an alteration, also known as a mutation in the COL3A1 gene.
COL3A1 gene is the instruction for making collagen type III a tough fibre-like protein that makes up a third of our body protein. When this gene is altered, it causes a lack or deficiency of this collagen making the connective tissue less effective, particularly in skin, lung, uterus, intestine and the vascular system.
Because many individuals with vascular EDS (vEDS) are identified only after a severe complication or death, it is likely it did not come to medical attention and therefore goes undetected.
At present, the life span for affected individuals is a median age of about 51 years (49 for males and 53 for females) but with a very large range from 10 years to 80 years. The prevelance is estimated as 1/50,000 to 1/200,000.
