Ehlers Danlos Syndrome

Caitlyn Cornish

Introduction

  • 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)

Prognosis &

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.
