These authors, in their work, also determined the frequency of coexistence of individual antineuronal antibodies in the course of autoimmune encephalitis at the level of 3% for antibodies directed against NMDAR and CASPR2 antigens, 2% for antibodies directed against NMDAR and GABABR antigens, 1% for antibodies directed against antigens NMDAR and Hu, and 1% for antibodies directed against Hu and CV2 antigens [8,9,10,11,12] [Figure 2]. This evidence concerns the gene CNTNAP2 and autoimmune encephalitis.
