PMP22 and Charcot-Marie-Tooth disease type 1A: In detail, 20/67 (30%) were carriers of the heterozygote whole gene duplication, thus confirming the clinical diagnosis of CMT1A; 5/67 (7.4%) were carriers of the heterozygote whole gene deletion, confirming HNPP clinical diagnosis; and one was a carrier of a rare whole gene mosaic duplication of 1.5-Mb in heterozygous in PMP22 gene (MIM 601097), considered as pathogenic (Rautenstrauss et al., 1998) and thus responsible for CMT disease 1A, autosomal dominant (MIM 118220).
