Charcot-marie-tooth Disease, Axonal, Autosomal Recessive, Type 2a2b; Cmt2a2b

Description

Autosomal recessive axonal CMT2A2B is a neurologic disorder characterized by onset of peripheral neuropathy in the first years of life. Patients have difficulty walking due to distal muscle weakness; upper limbs may also be affected. Sensory impairment is more variable. Patients often have optic atrophy (summary by Polke et al., 2011).
