In comparison to HC, atypical CIDP patients showed significantly higher SFU for the following peripheral myelin antigens: PMP-22 32-51 (patypical < 0.05), PMP-22 51-64 (patypical < 0.01), PMP-22 120-130 (patypical < 0.01), P2 14-25 (patypical < 0.01), P0 180-199 (patypical < 0.05), MBP 82-100 (patypical < 0.01) (Fig. 2). Here, PMP22 is linked to chronic inflammatory demyelinating polyradiculoneuropathy.
