| pubmed-article:8353419 | pubmed:abstractText | Charcot-Marie-Tooth disease type 1A, the most common inherited peripheral neuropathy, is associated with a submicroscopic DNA duplication of 1.5 Mb that can arise de novo, and which is flanked by a > 17 kb mosaic repeat. The PMP22 gene, encoding a peripheral myelin protein, maps within the duplication. In a subset of Charcot-Marie-Tooth patients, point mutations can occur within the gene. Thus, the alternative mechanisms of overexpression of PMP22 and structural alterations in the protein encoded can cause the disease phenotype. | lld:pubmed |
