More data are available for the polyneuropathy with antibodies to myelin-associated glycoprotein (MAG), but increasing evidence is also emerging for other immune-mediated diseases of the peripheral nervous system, including chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and autoimmune neuropathies with antibodies to nodal and paranodal antigens. Here, MAG is linked to chronic inflammatory demyelinating polyradiculoneuropathy.
