- Abstract
- Contactin-associated protein-like 2 (CASPR2) is one of the target antigens of voltage-gated potassium channels (VGKC) complex antibodies. There has been relatively little information in the literature regarding CASPR2 auto-immunity, especially in Asian population. We investigated the presence of CASPR2 antibodies in patients with presumed autoimmune neurological disorders and described the clinical features, laboratory findings, and responses to immunotherapy. Five patients were identified to be positive for CASPR2 antibodies. The results obtained here suggested that CASPR2 antibodies might be the possible cause of epilepsy even in the absence of typical features of limbic encephalitis and that immunotherapy could provide a favorable outcome.
