Polyneuropathy associated with IgM monoclonal gammapathy with anti-MAG

Polyneuropathy associated with IgM monoclonal gammapathy (MG) with anti-MAG (myelin-associated-glycoprotein) activity is a demyelinating polyneuropathy characterized clinically by sensory ataxia, tremor, paresthesia, and impaired gait.
