NFASC and autoimmune neuropathy: In these auto-immune neuropathies, antibodies target nodal and paranodal cell adhesion molecules; contactin 1 (CNTN1) (118), contactin-associated protein 1 (Caspr1) (119), neurofascin 155 (NF155) (120), neurofascin 140 (NF140) and 186 (NF186), also called pan-neurofascin when all isoforms of neurofascin are targeted (panNF) (121).
