Silver syndrome (Silver spastic paraplegia syndrome) is a rare disorder of the peripheral nervous system that combines features of spastic paraparesis and peripheral neuropathy. The underlying genetic defects are two mutations in the BSCL2 gene which have been described in several families. Silver syndrome--related to the N88S mutation in the BSCL2 gene--is characterized by a spectrum of clinical findings. The coexistence of sensory fiber damage and motor deficit leads to the diagnosis of Charcot-Marie-Tooth disease in some patients, while others are diagnosed with spastic paresis due to predominant pyramidal symptoms. If the symptoms are limited to the motor deficit, hereditary motor neuropathy is diagnosed in some cases. In this report, we describe a case of the Silver syndrome in a Polish family that has been verified by genetic testing. Due to the lack of pyramidal symptoms and slightly expressed sensory fiber damage (in neurographic studies), motor neuropathy type of the Silver syndrome with minor sensory component was diagnosed.

Heterozygous mutations in the Berardinelli-Seip congenital lipodystrophy 2 (BSCL2) gene have been reported with different clinical phenotypes including Silver syndrome (SS)/spastic paraplegia 17 (SPG17), distal hereditary motor neuropathy type V (dHMN-V), and Charcot-Marie-Tooth (CMT) disease type 2. We screened 407 Japanese patients who were clinically suspected of having CMT by exome sequencing and searched mutations in BSCL2. As a result, we identified five patients with heterozygous mutations in BSCL2. We confirmed three cases of known mutations (p.N88S and p.S90L) and two cases of novel mutations (p.N88T and p.S141A). The clinical features of the cases with known mutations in Japan were similar to those previously reported in other countries. In particular, there were many cases with sensory disturbance. The case with p.N88T mutation showed severe phenotype such as early onset age and prominent vocal cord paresis. The case with p.S141A mutation showed characteristics of demyelinating neuropathy such as CMT disease type 1 by electrophysiological examination. In this article, we report the clinical features and spread of cases with BSCL2 mutation in a Japanese cohort.
