Ehlers-Danlos syndrome

Ehlers-Danlos syndrome (EDS) is a group of inherited disorders marked by extremely loose joints, very stretchy (hyperelastic) skin that bruises easily, and easily damaged blood vessels.

Causes

There are six major types and at least five minor types of EDS.

A variety of gene changes (mutations) cause problems with collagen. This is the material that provides strength and structure to:

  • Skin
  • Bone
  • Blood vessels
  • Internal organs

The abnormal collagen leads to the symptoms associated with EDS. In some forms of the syndrome, the rupture of internal organs or abnormal heart valves can occur.

Family history is a risk factor in some cases.

Symptoms

Symptoms of EDS include:

  • Back pain
  • Double-jointedness
  • Easily damaged, bruised, and stretchy skin
  • Easy scarring and poor wound healing
  • Flat feet
  • Increased joint mobility, joints popping, early arthritis
  • Joint dislocation
  • Joint pain
  • Premature rupture of membranes during pregnancy
  • Very soft and velvety skin
  • Vision problems

Exams and Tests

Examination by a health care provider may show:

  • Deformed surface of the eye (cornea)
  • Excess joint looseness and joint hypermobility
  • Mitral valve in the heart does not close tightly (mitral valve prolapse)
  • Gum infection (periodontitis)
  • Rupture of intestines, uterus, or eyeball (seen only in vascular EDS, which is rare)
  • Soft, thin, or very stretchy skin

Tests to diagnose EDS include:

  • Collagen typing (performed on a skin biopsy sample)
  • Collagen gene mutation testing
  • Echocardiogram (heart ultrasound)
  • Lysyl hydroxylase or oxidase activity (to check collagen formation)

Treatment

There is no specific cure for EDS. Individual problems and symptoms are evaluated and cared for appropriately. Physical therapy or evaluation by a doctor specializing in rehabilitation medicine is often needed.

Support Groups

More information and support for people with Ehlers-Danlos and their families can be found at:

Outlook (Prognosis)

People with EDS generally have a normal life span. Intelligence is normal.

Those with the rare vascular type of EDS are at greater risk for rupture of a major organ or blood vessel. These people have a high risk for sudden death.

Possible Complications

Possible complications of EDS include:

  • Chronic joint pain
  • Early-onset arthritis
  • Failure of surgical wounds to close (or stitches tear out)
  • Premature rupture of membranes during pregnancy
  • Rupture of major vessels, including a ruptured aortic aneurysm (only in vascular EDS)
  • Rupture of a hollow organ such as the uterus or bowel (only in vascular EDS)
  • Rupture of the eyeball

When to Contact a Medical Professional

Call for an appointment with your provider if you have a family history of EDS and you are concerned about your risk or are planning to start a family.

Call for an appointment with your provider if you or your child has symptoms of EDS.

Prevention

Genetic counseling is recommended for prospective parents with a family history of EDS. Those planning to start a family should be aware of the type of EDS they have and its mode of how it is passed down to children. This can be determined through testing and evaluations suggested by your provider or genetic counselor.

Identifying any significant health risks may help prevent severe complications by vigilant screening and lifestyle alterations.

    This picture shows the unusually elastic skin (can be stretched much further than normal skin) of a patient with Ehlers-Danlos syndrome, a condition that affects connective tissues. This condition also causes skin to be easily bruised, heal poorly, form cigarette paper scars, and joints that are unusually flexible (hyperflexible, hypermobile).
