Abstract Charcot–Marie–Tooth neuropathy (CMT) is an extremely common but
heterogeneous inherited neuropathy. It has been classified into two forms: demyelinating
and axonal. The dominant axonal form, CMT2, has been further subdivided through linkage
study and 15 loci and 10 genes have been reported. For the glycyl-tRNA synthetase (GARS)
gene, a CMT2-causing gene, 10 mutations have been reported to date. We studied the

Abstract
Charcot–Marie–Tooth neuropathy (CMT) is an extremely common but heterogeneous inherited neuropathy. It has been classified into two forms: demyelinating and axonal. The dominant axonal form, CMT2, has been further subdivided through linkage study and 15 loci and 10 genes have been reported. For the glycyl-tRNA synthetase (GARS) gene, a CMT2-causing gene, 10 mutations have been reported to date. We studied the GARS in 89 Japanese patients with axonal CMT and detected a novel heterozygous Pro244Leu (c. 893C> T) mutation in a patient showing adolescent onset and early upper limb involvement. Results of our study indicate that GARS mutation is a rare cause of CMT2 among Japanese patients.
