Antibodies recognizing NF155, the glial isoform of NF, are associated with a subacute to chronic onset and progressive symptoms reminiscent of distal CIDP with symmetric, predominantly distal weakness, sensory loss, and gait ataxia as well as tremor are characteristic for anti-NF155-mediated AN [19,27,28,29]. This evidence concerns the gene NFASC and chronic inflammatory demyelinating polyradiculoneuropathy.
