The Ehlers Danlos Syndromes are a group of 13 heritable connective tissue disorders.
The 13 recognized Ehlers Danlos syndromes are Classical (cEDS), Classical-like (clEDS), Hypermobile (hEDS), Vascular (vEDS), Cardiac-valvular (cvEDS), Periodontal (pEDS), Kyphoscoliotic (kEDS), Spondylodysplastic (dEDS), Arthrochalasia (aEDS), Musculocontractural (mcEDS), Dermatosparaxis (dEDS), Myopathic (mEDS), and Brittle Cornea Syndrome (BCS).
The Ehlers Danlos Syndromes are typically characterized by joint laxity/hypermobility, tissue fragility, and skin hyperextensibility, generally accompanied by chronic musculoskeletal pain and frequent joint subluxations/dislocations.
