Demographically our patients are similar to other MOG cohorts (1–4, 8) in terms of a balanced gender distribution (64% female vs. 44–68%), onset age (29 vs. 27–37 years) and rate of comorbid autoimmune disorders (7 vs. 7–11%), but our cohort had a higher proportion of non-Caucasian patients (47 vs. 8–27%). Here, MOG is linked to autoimmune disease.
