Living with Proximal myopathy with extrapyramidal signs

A rare genetic condition with muscle weakness near the center of the body, learning problems, and movement disorders.

Understanding Proximal myopathy with extrapyramidal signs

Proximal myopathy with extrapyramidal signs is a rare genetic disorder with muscle weakness and movement problems that start in early childhood.

It causes weakness in the muscles closest to the center of the body, and learning disabilities. The weakness does not progress. Most people develop worsening involuntary muscle movements that affect walking, movement, and posture, which can be disabling. Symptoms vary.

Signs & symptoms

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

  • Weakness in the upper arms and thighs
  • Jerky, uncontrolled movements (chorea)
  • Tremor at rest
  • Abnormal postures (dystonia)
  • Walking difficulty
  • Delays in development

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 MICU1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
