Anti‐NMDAR encephalitis was the most common subtype, followed by anti‐LGI1, anti‐GABABR, and anti‐Caspr2 encephalitis, which is in agreement with previous reports (Gable, Sheriff, Dalmau, Tilley, & Glaser, 2012; van Sonderen et al., 2017). The gene discussed is CNTNAP2; the disease is viral encephalitis.
