Living with Astley-Kendall dysplasia

A rare genetic bone condition present from birth with very short limbs and brittle bones.

Understanding Astley-Kendall dysplasia

Astley-Kendall dysplasia is a rare skeletal dysplasia (a bone growth condition) with short arms and legs, fragile bones, and speckled calcium in cartilage.

It affects how bones form, leading to short limbs and brittle bones (osteogenesis imperfecta). It is seen during pregnancy and in newborns.

Signs & symptoms

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

  • Short limbs with short stature
  • Smaller or shorter limbs (micromelia)
  • Speckled calcium at the ends of bones (epiphyseal stippling)
  • Differences in how the skull bones formed

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 bone and joint specialists and genetic specialists.

  3. Ask which tests can help

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