Living with Roussy-Lévy syndrome

A rare inherited nerve condition starting in infancy or childhood with unsteady walking, foot differences, and weakness in the hands and feet.

Understanding Roussy-Lévy syndrome

Roussy-Lévy syndrome is a rare inherited nerve condition that affects movement and feeling.

Symptoms start in infancy or childhood. They include unsteady walking, high-arched feet, missing reflexes, weakness in the arms and legs, hand tremor, and loss of feeling in hands and feet. Muscles waste over time and the spine may curve.

Signs & symptoms

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

  • Unsteady walking (gait ataxia)
  • High-arched feet (pes cavus)
  • Missing tendon reflexes
  • Weakness and wasting of the hands and feet
  • Reduced pain, temperature, and vibration sense
  • Curved spine (kyphoscoliosis)

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

    Hereditary Neuropathy Foundation Inc., Charcot-Marie-Tooth Association and The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.
