Keratoderma Palmoplantar Spastic Paralysis

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