There are six major types of EDS. The different types of EDS are classified according to the signs and symptoms that are manifested. Each type of EDS is a distinct disorder that "runs true" in a family. This means that an individual with Vascular Type EDS will not have a child with Classical Type EDS. More detailed information can be found in our Medical Professionals Section.

General Frequently Asked Questions
Hypermobility (Formerly EDS Type III)

Joint hypermobility is the dominant clinical manifestation. Generalized joint hypermobility that affects large (elbows, knees)and small (fingers and toes) joints is evident in the Hypermobility Type. Recurring joint subluxations and dislocations are common occurrences. Certain joints, such as the shoulder, patella, and temporomandibular joint dislocate frequently. The skin involvement (hyperextensibility and/or smooth velvety skin) as well as bruising tendencies in the Hypermobility Type are present but variable in severity.

Chronic joint and limb pain is a common complaint amongst individuals with the Hypermobility Type. Skeletal X-rays are normal. Musculoskeletal pain is early onset, chronic and may be debilitating. The anatomical distribution is wide and tender points can sometimes be elicited.

To date, no distinctive biochemical collagen finding has been identified by researchers. The Hypermobility Type of EDS is inherited in an autosomal dominant manner.
