Ehlers-Danlos syndrome is a group of disorders that affect connective tissues supporting the skin, bones, blood vessels, and many other organs and tissues.
Defects in connective tissues cause the signs and symptoms of these conditions, which range from mildly loose joints to life-threatening complications.
Molecular Mechanisms
COL5A1 & COL5A2: classical
COL1A1: classical & vascular
TNXB: classical & hypermobile
COL1A2: cardiac-valvular & anthrochalasia
COL3A1: vascular
ADAMTS2: dermatosparaxis
PLOD1 & FKBP14: kyphoscoliotic
Diagnostic Technology
Collagen typing (performed on a skin biopsy sample)
Collagen gene mutation testing
Echocardiogram
Lysyl hydroxylase or oxidase activity (to check collagen formation)

Therapy
Prognosis & Therapy
There is no cure. Generally have a normal lifespan. Except, vascular types are at risk of rupturing a major blood vessel or organ.
Treatment involves managing symptoms, often with medicines and physical therapy. It also includes learning how to protect your joints and prevent injuries.
