MYELIN ASSOCIATED GLYCOPROTEIN- SULFATED GLUCURONIC PARAGLOBOSIDE AUTOANTIBODY (MAG-SGPG), IgM

Myelin associated glycoprotein (MAG) and sulphated glucuronyl paragloboside (SGPG) antibodies are present in a subgroup of sensory demyelinating neuropathies. Axonal neuropathies can present with only monoclonal IgM anti-SGPG activity. Presence of anti-SGPG antibodies alone is more characteristic of axonal non-demyelinating neuropathy. There is a relationship between the titer of anti-MAG antibodies and the degree of demyelination.
