Clinical Significance

Myasthenia Gravis is a neurological disorder characterized by a decrease in acetylcholine receptors. Patients exhibit skeletal muscle weakness and fatigability. Approximately 80% of patients with Myasthenia Gravis, excluding ocular involvement only, have detectable acetylcholine receptor antibody. There is a strong correlation between the presence of striated muscle antibody and the presence of thymoma.
