Type 4 is less common and often limited to certain ethnic groups. Patients present with the typical CMT phenotype along with typical features of progressive, distally accentuated weakness and atrophy of muscles innervated by the peroneal nerve in the lower limbs, followed by weakness and atrophy of hands, sensory loss, and characteristic foot abnormalities.\Charcot-Marie-Tooth disease type 4A (CMT4A) is a subtype of Charcot-Marie-Tooth disease type 4 characterized by early-onset (infancy to early childhood) of severe, rapidly progressing demyelinating, axonal, or intermediate sensorimotor neuropathy usually affecting first, and more severely, the distal lower extremities and later the proximal muscles and upper extremities. Nerve conduction velocities range from very slow to normal. Apart from the typical CMT phenotype (distal muscle weakness and atrophy, sensory loss, frequent pes cavus foot deformity), patients commonly present delayed motor development, vocal cord paresis, mild sensory loss, abolished deep tendon reflexes, and skeletal deformities.
