Living with Ataxia - intellectual disability - oculomotor apraxia - cerebellar cysts syndrome

A rare genetic condition with steady balance problems, developmental delay, and eye movement and vision problems.

Understanding Ataxia - intellectual disability - oculomotor apraxia - cerebellar cysts syndrome

Ataxia-intellectual disability-oculomotor apraxia-cerebellar cysts syndrome is a rare genetic condition that affects balance, learning, and the eyes.

People have ataxia (balance and coordination trouble) that does not get worse over time, delayed motor and language development, and intellectual disability. Eye problems can include trouble starting eye movements (oculomotor apraxia), crossed eyes, lazy eye, retinal changes, and nearsightedness. Brain scans show cysts and differences in the cerebellum. It is noticed in newborns and infants.

Signs & symptoms

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

  • Trouble with balance and coordination (ataxia)
  • Delayed development
  • Intellectual disability
  • Trouble starting eye movements (oculomotor apraxia)
  • Crossed eyes (strabismus) and lazy eye (amblyopia)
  • Fluid-filled cysts in the cerebellum

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 brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in LAMA1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Recessive
GenesLAMA1

GARD says changes in the LAMA1 gene cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
