PMP22 and chronic inflammatory demyelinating polyradiculoneuropathy: The distal acquired demyelinating symmetric (DADS) neuropathy phenotype was significantly more frequent in NF155+ than in NF155− CIDP (46.2 vs. 4.9%); however, the clinical subtype of NF155+ CIDP was not only confined to the DADS phenotype but was also associated with proximal nerve involvement presenting as the typical CIDP phenotype.
