We are grateful for the interest of Kambe and colleagues in our article regarding adult-onset opsoclonus-myoclonus syndrome (OMS).1 In our literature search, we had encountered 2 patients with antibody targeting the GluN1 subunit (NR1 subunit) of the N -methyl-D-aspartate (NMDA) receptor.2,3 In addition to the unusual finding of OMS in these 2 patients, both had a neuropsychiatric presentation typical of anti–NMDA receptor encephalitis.
