Charcot-Marie-Tooth disease type 1C

Definition

A rare, autosomal dominant, hereditary, demyelinating motor and sensory neuropathy which may present either as a classic Charcot-Marie-Tooth disease phenotype with distal motor weakness and wasting, gait difficulties, parethesias, decreased vibration and pain sensation, or as a milder, predominantly sensory form with transient paresthesias, decreased sensation and distal pain in upper or lower limbs, without significant motor weakness. Pes cavus is a common feature, and additional symptoms may include hand tremor and decreased or absent deep tendon reflexes.
