AQP4 autoantibody
Neuromyelitis optica (NMO) is an immune-mediated chronic inflammatory disease of the central nervous system (CNS). Clinically, it presents with optic neuritis (ON) and myelitis, often characterized by recurrent episodes of optic neuritis (ON) and transverse myelitis (TM), often results in blindness or paraplegia with poor or no recovery. A serum immunoglobulin G autoantibody, NMO-IgG (also termed aquaporin- 4 antibody, AQP4-Ab) has been shown to be a specific marker for NMO patient. Measurement of AQP4 Ab can be of considerable value in distinguishing NMO from MS when full clinical features may not be apparent and early intervention.
