Abstract:
The purpose of this research is to explore the underlying genes of Charcot-Marie-Tooth (CMT). Technologies such as electrophysiological testing and gene sequencing have been applied. We identified a novel variant NEFH c.2215C>T(p.P739S)(HGNC:7737) in a heterozygous state, which was considered to be pathogenic for CMT2CC(OMIM:616924).The proband and his brothers presented with muscle atrophy of hand and calf and moderately decreased conduction velocities. By whole exome sequencing analysis, we found the novel missense pathogenic variant in the proband, his brother and mother. This report broadened current knowledge about intermediate CMT and the phenotypic spectrum of defects associated with NEFH. In addition, the proband carried other five variants {HSPD1c.695C>A (p.S232X), FLNCc.1073A>G (p.N358S), GUSBc.323C>A (p.P108Q), ACY1 c.1063-1G>A and APTX c.484-2A>T}, which have not been reported until now. The NEFH c.2215C>T (p.P739S) give us a new understanding of CMT, which might provide new therapeutic targets in the future.
