Charcot-Marie-Tooth disease axonal type 2U (MONDO_0014566) can be described as follows. Autosomal dominant Charcot-Marie-Tooth disease type 2U (CMT2U) is a subtype of autosonal dominant Charcot-Marie-Tooth disease type 2 characterized by late adult-onset (50-60 years of age) of slowly progressive, axonal, peripheral sensorimotor neuropathy resulting in distal upper limb and proximal and distal lower limb muscle weakness and atrophy, in conjunction with distal, panmodal sensory impairment in upper and lower limbs. Tendon reflexes are reduced and nerve conduction velocities range from reduced to absent. Neuropathic pain has also been associated. Also known as: CMT2U, Charcot-Marie-Tooth disease type 2 caused by mutation in MARS, Charcot-Marie-Tooth neuropathy type 2U, MARS Charcot-Marie-Tooth disease type 2, autosomal dominant Charcot-Marie-Tooth disease type 2 due to MARS mutation, autosomal dominant Charcot-Marie-Tooth disease type 2U, autosomal dominant axonal Charcot-Marie-Tooth disease type 2U.
