Living with Neuronopathy, distal hereditary motor, autosomal dominant 1
A rare inherited nerve and muscle condition with slowly worsening weakness in the lower legs, without loss of feeling.
Understanding Neuronopathy, distal hereditary motor, autosomal dominant 1
It causes slowly worsening weakness and wasting of the muscles in the lower legs, without loss of sensation. Other features may include high-arched feet, hammertoes, and increased muscle tone. GARD lists onset from childhood to adulthood.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Weakness in the muscles farthest from the center of the body
- Wasting of muscles in the hands and feet
