Living with Autosomal recessive spinocerebellar ataxia 11

A rare inherited condition with slowly worsening balance and speech problems, with delayed development in childhood.

Understanding Autosomal recessive spinocerebellar ataxia 11

Autosomal recessive spinocerebellar ataxia 11 is a rare inherited condition with slowly worsening balance problems that start later in life after delays in childhood.

People have slowly worsening walking problems, unclear speech, and poor coordination of the arms, legs, and trunk. There is a history of developmental delay from childhood. Brain scans show mild shrinking of the cerebellum. Onset is listed as childhood.

Signs & symptoms

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

  • Balance and coordination problems (ataxia)
  • Unsteady walk
  • Unclear speech (dysarthria)
  • Shaky eye movements (nystagmus)
  • Global developmental delay
  • Trouble swallowing (dysphagia)

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 SYT14 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.

Quick facts

Symptoms usually startChild
InheritanceAutosomal Recessive
GenesSYT14

It is caused by changes in the SYT14 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
