Living with Spondylo-ocular syndrome

A very rare genetic condition with cataracts, retinal detachment, weak bones and flattened spine bones.

Understanding Spondylo-ocular syndrome

Spondylo-ocular syndrome is a very rare condition that combines spine and eye differences.

It is characterized by dense cataracts and retinal detachment, along with generalized osteoporosis and flattened spine bones (platyspondyly). Mild facial differences have been reported, including a short neck, a large head and prominent eyebrows. Signs start in the newborn and infant period.

Signs & symptoms

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

  • Cataracts
  • Retinal detachment
  • Vision loss
  • Weak bones (osteoporosis)
  • Flattened spine bones
  • Short neck and short trunk

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 XYLT2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
