Living with Charcot-Marie-Tooth disease recessive intermediate C

A rare inherited nerve condition with weakness, foot differences, and loss of feeling, starting anytime from childhood to adulthood.

Understanding Charcot-Marie-Tooth disease recessive intermediate C

Charcot-Marie-Tooth disease recessive intermediate C is a rare, inherited nerve disease affecting movement and feeling.

It causes moderate to severe, slowly worsening weakness and wasting mostly in the lower legs, foot differences such as high arches and hammertoes, absent reflexes, and loss of feeling. It can start at any time from childhood on.

Signs & symptoms

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

  • Wasting of muscles in the hands and feet
  • Absent tendon reflexes
  • Loss of feeling in the hands and feet
  • High-arched feet (pes cavus)
  • Hammertoes
  • High-stepping walk and scoliosis

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 PLEKHG5 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

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