Myelin Oligodendrocyte Glycoprotein Antibody

Myelin oligodendrocyte glycoprotein is a CNS antigen expressed on the myelin sheath. Approximately 5% of patients with neuromyelitis optica spectrum disorder (NMOSD) test negative for anti-neuromyelitis optica antibody (anti-AQP4) but have detectable antibodies against myelin oligodendrocyte glycoprotein (anti-MOG). Patients with anti-MOG antibodies have some different clinical features than patients who are positive for anti-NMO antibodies such as:

  • Proportionally more men affected
  • More frequent simultaneous bilateral optic neuritis
  • Fewer painful tonic spasms
  • Spinal cord lesions mainly occur in the lower portion of the spinal cord

Patients who are positive for anti-MOG antibody tend to have better outcomes than those who are anti-AQP4-positive.
