Several other autoantibodies against multiple neuronal autoantigens have been discovered in autoimmune encephalitis (AE) disease [3–5], including anti-gamma-aminobutyric acid-B receptor (GABABR) encephalitis, anti-leucine-rich glioma-inactivated 1 (LGI1) encephalitis, and anti-contactin-associated protein-like 2 (CASPR2) encephalitis. This evidence concerns the gene CNTNAP2 and autoimmune encephalitis.
