KCNQ1 and viral encephalitis: Kcnq1ot1, a long chromatin‐interacting noncoding RNA that silences ubiquitously imprinted genes in the Kcnq1 domain via establishing a repressive higher‐order chromatin structure [39, 40], was found significantly changed in hippocampal inhibitory neurons from anti‐NMDAR encephalitis models in this study.
