Abstract:
:Charcot-Marie-Tooth disease type 1 (CMT1) is a heterogeneous disorder. Most CMT1 patients are associated with a duplication of 17p11.2-p12 (CMT1A duplication), but a small number of patients have mutations of peripheral myelin protein 22 (PMP22), myelin protein zero (MPZ), connexin 32 (Cx32) and early growth response 2 (EGR2) genes. In our previous study, we identified the responsible mutations in 72 of 128 Japanese CMT1 patients as CMT1A duplication in 40, PMP22 mutation in 6, MPZ mutation in 12 and Cx32 mutation in 14 patients. A total of 56 Japanese CMT1 patients with no identified mutations were screened for EGR2 mutation by denaturing gradient gel electrophoresis (DGGE). We detected a heterozygous Asp383Tyr mutation of EGR2 in one patient with severe CMT1, Dejerine-Sottas syndrome. EGR2 mutation is rare cause of CMT1 in Japan as in other nations. We were unable to identify the responsible mutation in 55 of 128 CMT1 patients and need further analysis to identify their candidate genes.
