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

Neuronopathy, distal hereditary motor, autosomal dominant 1 (distal hereditary motor neuropathy type 1) is a rare nerve and muscle condition.

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
  • Arm weakness
  • High-arched feet (pes cavus)
  • Hammertoes
  • Increased muscle tone

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. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.
