Ehlers-Danlos syndrome is a group of connective tissue disorders characterized by skin hyperextensibility, atrophic scarring, and generalized joint hypermobility. Other features include hypotonia with delayed motor development, fatigue and muscle cramps, and easy bruising. These symptoms manifest at birth or in early childhood. Complications may include aortic dissection, joint dislocations, scoliosis, or early osteoarthritis.

The prevalence of all types of Ehlers-Danlos syndrome appears to be at least 1 in 5000 individuals worldwide.

Ehlers-Danlos syndrome can have either an autosomal dominant or autosomal recessive pattern of inheritance, varying by the type of the disease.
