Distal Hereditary Motor Neuropathy Type V (dHMN-V) With N88S Mutation in BSCL2 Gene

ABSTRACT

Berardinelli-Seip congenital lipodystrophy 2 (BSCL2) gene is known to be associated with different clinical phenotypes; Silver syndrome, Charcot-Marie-Tooth type 2 with a dominant hand involvement and distal hereditary motor neuropathy type V (dHMN-V). Up to now, only two heterozygous mutations (N88S and S90L) in BSCL2 have been reported. We identified a N88S BSCL2 mutation in a dHMN-V family with a spastic gait by whole-exome sequencing. To our knowledge, this is the first report of a N88S BSCL2 mutation in Korean patient.
