Charcot -Marie-Tooth disease is a group of inherited disorders that cause nerve damage. This damage is mostly in the arms and legs (peripheral nerves). It is also called hereditary motor and sensory neuropathy. It generally leads to smaller, weaker muscles, loss of sensation and muscle contractions, and difficulty walking. Foot deformities such as hammertoes and high arches also are common. Symptoms usually begin in the feet and legs, but they may eventually affect your hands and arms.


Signs and symptoms of Charcot-Marie-Tooth disease may include:Uploaded Image

  • Weakness in your legs, ankles and feet
  • Loss of muscle bulk in your legs and feet
  • High foot arches
  • Curled toes (hammertoes)
  • Decreased ability to run
  • Difficulty lifting your foot at the ankle (footdrop)
  • Awkward or higher than normal step (gait)
  • Frequent tripping or falling
  • Decreased sensation or a loss of feeling in your legs and feet

CAUSES - It is usually an autosomal dominant disorders but can be recessive or X-linked. Type I results from a duplication (extra copy) of the peripheral myelin protein-22 gene (PMP22), located on the short arm of chromosome 17; it accounts for 70 to 80% of CMT1 cases. Sometimes, these mutations damage the nerves. Other mutations damage the protective coating that surrounds the nerve (myelin sheath). Both cause weaker messages to travel between your limbs and brain.
