de Meel and colleagues defined distinct phenotypes of MG based on combinations of muscle weakness: ocular, bulbar, neck/limbs/respiratory, or a combination. Patients with MG have heterogeneous distributions of muscle weakness and may shift between phenotypes over time.

The distribution of clinical weakness represents one factor in the classification of patients with MG into various subgroups. MG subgroups are also based on the profile of serum autoantibodies, the age of disease onset, and the presence or absence of thymic pathology.
