In other examples of strong genetic predisposition, anti-LGI1 encephalitis shows a strong HLA association with the DRB1*07:01 allele, which is carried by 90% of patients vs. 13% of healthy controls (11); anti-IgLON5 disease is tightly associated with the DRB1*10.01 allele (12); CASPR2-antibody patients show over representation of HLA-DRB1*11:01 (13); MUSK-Myasthenia gravis is tightly associated with the HLADR14-DQ5 haplotype (14) and early onset anti-AChR MG with HLA-B*8:01 and late onset MG with HLA DRB1* 15:01 (15). The gene discussed is CNTNAP2; the disease is viral encephalitis.
