Living with Spinocerebellar ataxia type 27

A very rare inherited condition with tremor starting early and slowly worsening coordination problems.

Understanding Spinocerebellar ataxia type 27

Spinocerebellar ataxia type 27 (SCA27) is a very rare type of dominantly inherited cerebellar ataxia.

It features tremor that starts early, abnormal involuntary movements (dyskinesia) and slowly worsening poor coordination. Symptoms can also include slurred speech, memory trouble and nerve damage. It starts in the teens or adulthood.

Signs & symptoms

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

  • Tremor
  • Poor coordination and unsteady walk
  • Slurred speech (dysarthria)
  • Jerky eye movements (nystagmus)
  • Memory problems
  • High-arched feet

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 FGF14 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.

  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Can genetic testing of the FGF14 gene confirm this diagnosis?
What can help with tremor and involuntary movements?
Should memory and mood be monitored?

Quick facts

InheritanceAutosomal Dominant
GenesFGF14

GARD lists changes in the FGF14 gene. It is inherited in an autosomal dominant pattern, meaning one changed copy of the gene is enough.
