Living with Childhood-onset motor and cognitive regression syndrome with extrapyramidal movement disorder

A rare genetic brain condition beginning in childhood that gradually affects movement, thinking, and speech.

Understanding Childhood-onset motor and cognitive regression syndrome with extrapyramidal movement disorder

Childhood-onset motor and cognitive regression syndrome with extrapyramidal movement disorder is a rare genetic disease of the brain and nervous system.

It usually shows up in childhood and gets worse over time. It causes problems with movement and thinking, which can lead to intellectual disability and trouble with language and walking. Head size may fall behind over time. Brain imaging may show loss of brain cells in the cerebrum and cerebellum, and the corpus callosum may be affected.

Signs & symptoms

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

  • Involuntary muscle contractions (dystonia)
  • Muscle stiffness (spasticity)
  • Loss of skills already learned (developmental regression)
  • Slurred or hard-to-form speech (dysarthria)
  • Trouble swallowing (dysphagia)
  • Seizures

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

Quick facts

InheritanceAutosomal Dominant
GenesUBTF

GARD says changes in the UBTF gene cause this condition. It is autosomal dominant, so one changed copy of the gene can be enough.
