About Myelin associated glycoprotein antibodies

What is myelin-associated glycoprotein?

Myelin-associated glycoprotein (MAG) is an important protein for myelin. Myelin is a fatty substance which surrounds and protects nerves and is produced by two types of cell: Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.

Antibodies against MAG are associated with sensory and motor neuropathies. Antibodies are proteins typically produced by the immune system to target and protect against harmful entities. In some cases, the immune system can malfunction, producing antibodies which target and attack the body’s own cells.

MAG antibodies prevent the ability of myelin to function properly and can result in the loss of myelin. This subsequently affects nerve signalling resulting in neuropathies. Symptoms include sensory loss in the peripheries (hands and feet), unsteady gait, muscle weakness and tremors in the hands and legs.  

Why take this test?

This test detects the presence of MAG antibodies in the blood and can be used to help diagnose neuropathies associated with MAG antibodies.
