We also found that patients with MOG-Ab disease more commonly presented with multiple spinal cord lesions than patients with AQP4-Ab disease did, which agrees with results presented in a 2019 study by Dubey et al.14 Short cord lesions may be misdiagnosed as MS, particularly in pediatric populations, in which patients with MOG-Ab disease have received an MS misdiagnosis in the past.15 Therefore, axial imaging of the spinal cord is crucial in these cases, as is brain imaging. The gene discussed is MOG; the disease is glycogen storage disease VI.
