About Ehlers-Danlos Syndrome
Ehlers-Danlos syndrome (EDS) encompasses a group of genetic connective tissue disorders caused by mutations affecting collagen synthesis, structure, or processing. At least 13 subtypes are recognized, each with distinct genetic basis and clinical features.
Classical EDS, which is less common than hypermobile EDS, usually results from type V collagen variants and features hyperextensible skin, joint hypermobility, poor wound healing, and characteristic skin texture (velvety or doughy). Vascular EDS, caused by type III collagen mutations (COL3A1), is the most serious, characterized by thin translucent skin, easy bruising, severe joint hypermobility, and life-threatening complications including spontaneous aortic and arterial aneurysms, arterial rupture, and gastrointestinal perforation.
The combination of joint instability and tissue fragility creates challenges for treatment and high risk of complications. Molecular understanding of EDS subtypes has improved, allowing for genotype-phenotype correlation and tailored management strategies.
Common Symptoms of Ehlers-Danlos Syndrome
Recognizing the signs of Ehlers-Danlos Syndrome early can lead to faster diagnosis and better outcomes. Symptoms may vary in severity from person to person. If you or a loved one are experiencing any of the following, consider speaking with a specialist.
- Overly flexible joints (hypermobility) with dislocations
- Hyperextensible, velvety skin with poor wound healing
- Easy bruising and fragile tissues
- Aortic and arterial aneurysms in vascular EDS
- Gastrointestinal complications including perforations in vascular EDS
- Chronic pain and fatigue
Who Ehlers-Danlos Syndrome Affects
Various subtypes with different inheritance patterns; most are autosomal dominant. Hypermobile EDS (formerly Type III) is the most common type, followed by classical EDS (formerly Types I and II); vascular EDS (formerly Type IV) is the most serious. Affects males and females equally.
