More recently, Baglioni et al. (105) investigated the same patients tested by Addabbo et al. (103) plus a cohort of unaffected siblings of these patients, screening for autoantibodies associated with established encephalopathies (antibodies targeting NMDAR, CASPR2, LGI1, AMPAR, and GABAAR). This evidence concerns the gene LGI1 and Encephalopathy.
