Clinical Significance
Myasthenia gravis (MG) is a neuromuscular disorder
characterized by muscle weakness, most commonly due to
autoantibody-mediated loss of functional acetylcholine
receptors (AChR) in the neuromuscular junction.
Modulating Antibody to AChR causes weakness by inhibiting
or modulating binding to the receptors.
