Median MOG-IgG titers of seropositive patients were 1:2,560 (1:160-1:2,560) in NMO, 1:2,560 (1:640-1:5,120) in HR-NMO, 1:2,560 (1:160-1:20,480) in ADEM, 1:640 and 1:5,120 in CIS, 1:160 and 1:160 in MS and 1:320 (1:160-1:640) in CTRL (Figure 1 and Table 1). This evidence concerns the gene MOG and neuromyelitis optica.
