Living with Spondylodysplastic Ehlers-Danlos syndrome

A rare connective tissue condition with short stature, loose joints, stretchy skin, and low muscle tone.

Understanding Spondylodysplastic Ehlers-Danlos syndrome

Spondylodysplastic Ehlers-Danlos syndrome is a rare connective tissue condition with three subtypes linked to different genes.

Features that overlap across the subtypes include short stature that grows more noticeable in childhood and very flexible small joints. Skin is stretchy and soft, especially on the hands and feet. Muscle tone is low, from severe at birth to mild with later onset. Bone differences, thinner bones, delayed motor development, and bowed limbs can also occur. Signs may begin in the newborn or infant years.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Short stature that becomes clearer in childhood
  • Very flexible (double-jointed) joints
  • Soft, stretchy skin
  • Spine curving forward and to the side (kyphoscoliosis)
  • Clubfeet or flat feet
  • Delayed development

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists, genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Bobby Jones Chiari & Syringomyelia Foundation may keep lists of experts for this condition.

Changes in one of three genes, B4GALT7, B3GALT6, or SLC39A13, cause the three subtypes. GARD does not list an inheritance pattern here.
