Myasthenia gravis is an autoimmune disease mediated by pathogenic autoantibodies targeting specific antigens of the postsynaptic membrane (AChR and MuSK), or muscle antigens (titin, ryanodine receptor).
The diagnostic significance of autoantibodies directed against striated muscle is relevant when antibody titers are high, while low titers may indicate reduced disease activity.
Autoantibodies against striated muscle can also be present in patients with other myopathies and in those with Chagas disease.
