Chronic inflammatory demyelinating polyneuropathy: Some cases of CIDP are reported to be produced by auto-antibodies against several neurofascin proteins. These proteins are present in the neurons and four of them have been reported to produce disease: NF186, NF180, NF166 and NF155.[2]
Neuromyelitis optica: NF auto antibodies can also appear in NMO cases.[2] These antibodies are more related to the peripheral nervous demyelination, but they were also found in NMO.[3][non-primary source needed]
Multiple sclerosis: Also antibodies against Neurofascins NF-155 can also appear in atypical multiple sclerosis[4] and NF-186 could be involved in subtypes of MS[5] yielding an intersection between both conditions. Around 10% of MS cases are now thought to be anti-NF cases.[6][7]
