This difference between typical and atypical CIDP patients was more pronounced for PMP-22 32-51 (p = 0.0621), PMP-22 51-64 (p = 0.1050), PMP-22 120-130 (p = 0.1451), P0 180-199 (p = 0.1894) and MBP 82-100 (p = 0.1841) (Fig. 2). This evidence concerns the gene PMP22 and chronic inflammatory demyelinating polyradiculoneuropathy.
