Myasthenia gravis (MG) is a rare autoimmune disease mediated by pathogenic antibodies (Ab) directed against components of the neuromuscular junction (NMJ), mainly the acetylcholine receptor (AChR). Loss of these receptors leads to a defect in neuromuscular transmission with muscle weakness and fatigue. Myasthenia gravis is an autoimmune disorder mainly caused by antibodies to the muscle acetylcholine receptors (AChRs) at the neuromuscular junction. There is some evidence, however, that this “seronegative” MG is an antibody. 1375-1380. 51%, respectively. Gov't.
