Living with Spastic ataxia 3
A rare inherited nervous system condition with poor coordination, stiff muscles and brain changes.
Understanding Spastic ataxia 3
It also involves shrinking of the cerebellum (and sometimes the cerebrum), involuntary muscle movements (dystonia) and changes in the brain's white matter. Symptoms can start anywhere from childhood to adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Poor coordination when walking
- Stiff muscles (spasticity)
- Slurred speech
- Involuntary eye movements (nystagmus)
- Dystonia
- Mild intellectual disability
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 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 brain and nervous system specialists and genetic specialists.
- 3Consider genetic testing
Changes in MARS2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
- 4Connect with expert centers
National Ataxia Foundation, United Mitochondrial Disease Foundation and MitoAction may keep lists of experts for this condition.

Quick facts
GARD lists changes in the MARS2 gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
Also known as: arsal; arsal - autosomal recessive spastic ataxia with leukoencephalopathy; ataxia, spastic, 3, autosomal recessive; autosomal recessive spastic ataxia caused by mutation in mars2; autosomal recessive spastic ataxia type 3; autosomal recessive spastic ataxia with leukoencephalopathy
