PB - Academic Press M1 - DZNE-2024-00244 SP - 399 - 411 PY - 2024 AB - Autoantibodies against the potassium voltage-gated channel subfamily A member 2 (KCNA2) have been described in a few cases of neuropsychiatric disorders, but their diagnostic and pathophysiological role is currently unknown, imposing challenges to medical practice.We retrospectively collected comprehensive clinical and paraclinical data of 35 patients with KCNA2 IgG autoantibodies detected in cell-based and tissue-based assays. Patients' sera and cerebrospinal fluid (CSF) were used for characterization of the antigen, clinical-serological correlations, and determination of IgG subclasses.KCNA2 autoantibody-positive patients (n = 35, median age at disease onset of 65 years, range of 16-83 years, 74 KW - Animals KW - Humans KW - Male KW - Adolescent KW - Young Adult KW - Adult KW - Middle Aged KW - Aged KW - Aged, 80 and over KW - Female KW - Autoimmunity KW - Retrospective Studies KW - Autoantibodies KW - Seizures KW - Autoimmune Diseases of the Nervous System KW - Mammals KW - Kv1.2 Potassium Channel KW - Encephalitis KW - Hashimoto Disease KW - Autoantibody (Other) KW - Autoimmune dementia (Other) KW - Autoimmune encephalitis (Other) KW - Epilepsy (Other) KW - Immunotherapy (Other) KW - KCNA2 (Other) KW - Kv1.2 (Other) KW - Autoantibodies (NLM Chemicals) KW - KCNA2 protein, human (NLM Chemicals) KW - Kv1.2 Potassium Channel (NLM Chemicals) LB - PUB:(DE-HGF)16 C6 - pmid:38309639 DO - DOI:10.1016/j.bbi.2024.01.220 UR - https://pub.dzne.de/record/268498 ER -
