Living with Metaphyseal chondrodysplasia-retinitis pigmentosa syndrome

A rare inherited syndrome with short stature, short fingers and toes, and a progressive eye condition.

Understanding Metaphyseal chondrodysplasia-retinitis pigmentosa syndrome

Metaphyseal chondrodysplasia-retinitis pigmentosa syndrome, also called brachydactyly-short stature-retinitis pigmentosa syndrome, is a rare genetic limb and eye condition.

It has mild to severe short stature, short fingers and toes (brachydactyly), and breakdown of the retina, usually retinitis pigmentosa. Intellectual disability, delayed development, and facial differences vary. It starts in infancy and childhood.

Signs & symptoms

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

  • Short stature
  • Short fingers or toes (brachydactyly)
  • Retina breakdown (retinal degeneration)
  • Night blindness
  • Intellectual disability
  • Delayed speech and 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 bone and joint specialists, brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in CWC27 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
