Living with Spinocerebellar ataxia type 37

An inherited condition starting in adulthood with poor coordination and changes in up-and-down eye movements.

Understanding Spinocerebellar ataxia type 37

Spinocerebellar ataxia type 37 (SCA37) is a dominantly inherited cerebellar ataxia with changed vertical eye movements.

People have the poor coordination and balance problems of a cerebellar syndrome, with altered up-and-down eye movements. They may also have scanning speech, falls, tremor, muscle jerks and hearing loss. It starts in adulthood.

Signs & symptoms

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

  • Unsteady walk and falls
  • Poor trunk and limb coordination
  • Altered eye movements
  • Slow, scanning speech
  • Tremor
  • Muscle jerks (myoclonus)

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 and genetic specialists.

  3. Consider genetic testing

    Changes in DAB1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    National Ataxia Foundation may keep lists of experts for this condition.

GARD lists changes in the DAB1 gene. It is inherited in an autosomal dominant pattern, meaning one changed copy of the gene is enough.
