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
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.
