Living with Posterior fusion of lumbosacral vertebrae-blepharoptosis syndrome

A rare inherited syndrome with a drooping upper eyelid from birth and fused bones in the lower spine.

Understanding Posterior fusion of lumbosacral vertebrae-blepharoptosis syndrome

Posterior fusion of lumbosacral vertebrae-blepharoptosis syndrome is a rare syndrome with a drooping upper eyelid and fused bones at the back of the lower spine.

The droopy eyelid (ptosis) is present from birth. GARD says it can be seen in childhood. Other features include fused ankle bones, joint stiffness and a small dimple at the base of the spine.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Drooping upper eyelid (ptosis)
  • Fused bones in the lower back
  • Fused ankle bones
  • Joint stiffness
  • Dimple at the base of the spine

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 genetic specialists.

  3. Ask which tests can help

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