Mondo Description Autosomal dominant Charcot-Marie-Tooth disease type 2Q is a rare subtype of autosomal dominant Charcot-Marie-Tooth disease type 2 characterized by adolescent to adulthood-onset of symmetrical, slowly progressive distal muscle weakness and atrophy (with a predominant weakness of the distal lower limbs) associated with reduced or absent deep tendon reflexes, pes cavus and mild to moderated deep sensory impairment.

Uniprot Description An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy.
