CNTNAP2 and Autoimmunity: The human leukocyte antigen (HLA) is the main genetic factor related to autoimmunity, with several associations in neurological diseases driven by neural antibodies [90], being especially strong between DRB1*07:01 and limbic encephalitis (LE) with antibodies against leucine-rich glioma inactivated 1 [91,92,93,94] and between DRB1*11:01 and LE with antibodies against contactin-associated protein-like 2 (CASPR2) [93,95].
