Palmoplantar keratoderma-hereditary motor and sensory neuropathy syndrome

A rare, genetic, autosomal dominant hereditary axonal motor and sensory neuropathy disorder characterized by childhood-onset palmoplantar keratoderma associated with motor and sensory polyneuropathy manifestating with late-onset, predominantly distal, lower limb muscle weakness and atrophy (later associating mild proximal weakness and upper limb involvement), moderate sensory impairment (hypoesthesia with stocking-glove distribution), and normal or near‐normal nerve conduction velocities. Additional variable manifestations include impaired vibratory sensation, reduced tendon reflexes, paresthesia, pain, talipes equinovarus, pes cavus, and nail dystrophy.
