Living with Horizontal gaze palsy with progressive scoliosis
A genetic condition that affects side-to-side eye movement from birth and causes a curved spine that gets worse over time.
Understanding Horizontal gaze palsy with progressive scoliosis
People cannot move their eyes side to side from birth, so they turn their head to follow objects. Up-and-down eye movement is typically normal. Scoliosis develops between infancy and childhood and tends to worsen. It can be painful, and may need bracing or surgery. Brain imaging shows differences along the midline. Most people have normal intelligence, but mild intellectual disability can occur.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Cannot move eyes side to side
- Curved spine (scoliosis)
- Rounded upper back (kyphosis)
- Crossed eyes (strabismus)
- Fast, shaky eye movements (nystagmus)
- Low muscle tone (hypotonia)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include bone and joint specialists, brain and nervous system specialists, eye disease specialists and genetic specialists.
- 3Ask which tests can help
Your care team will decide which exams and tests can confirm the diagnosis.

Quick facts
Changes in genes (also called variants) cause this condition. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
Also known as: familial infantile scoliosis associated with bilateral paralysis of conjugate gaze; gaze palsy, familial horizontal, with progressive scoliosis; hgpps; hgpps - horizontal gaze palsy with progressive scoliosis; progressive external ophthalmoplegia and scoliosis
