In a study comparing outcomes of myelitis attacks in AQP4+NMOSD and MOGAD, the median EDSS at myelitis recovery was 3.0 (range 1.0–8.0) for AQP4+NMOSD and 1.8 (range 1–8.0) for MOGAD, with only 7% of patients having an EDSS ≥ 6 at recovery in the MOGAD group vs. 44% of the AQP4+NMOSD (26). The gene discussed is AQP4; the disease is myelitis.
