Ehlers-Danlos syndrome is a group of inherited disorders marked by extremely loose joints, hyperelastic skin that bruises easily, and easily damaged blood vessels.
There are six major types and at least five minor types of Ehlers-Danlos syndrome (EDS).
A variety of gene mutations (changes) cause problems with collagen, the material that provides strength and structure to skin, bone, blood vessels, and internal organs.
The abnormal collagen leads to the symptoms associated with EDS. In some forms of the condition this can include rupture of internal organs or abnormal heart valves.
Family history is a risk factor in some cases.
Symptoms of EDS include:
Examination by the health care provider may show:
Tests performed to diagnose EDS include:
There is no specific cure for Ehlers-Danlos syndrome. Individual problems and symptoms are evaluated and cared for appropriately. Frequently, physical therapy or evaluation by a doctor specializing in rehabilitation medicine is needed.
People with EDS generally have a normal life span. Intelligence is normal.
Those with the rare vascular type of EDS are at significantly increased risk for rupture of a major organ or blood vessel. These individuals, therefore, have a high risk of sudden death.
Possible complications of Ehlers-Danlos syndrome include:
Call for an appointment with your health care provider if you have a family history of Ehlers-Danlos syndrome and you are concerned about your risk or are planning to start a family.
Call for an appointment with your health care provider if you or your child have symptoms of EDS.
Genetic counseling is recommended for prospective parents with a family history of Ehlers-Danlos syndrome. Those planning to start a family should be aware of the type of EDS they have and its mode of inheritance (how it is passed down to children). This can be determined through testing and evaluation suggested by your health care provider or genetic counselor.
Identifying any significant health risks may help prevent severe complications by vigilant screening and lifestyle alterations.
