Outline of Final Research Achievements |
To investigated the frequency and contribution of variants of the 28 known amyotrophic lateral sclerosis (ALS)-related genes in Japanese ALS patients, we designed a multiplex, PCR-based primer panel to amplify the coding regions of the 28 ALS-related genes and sequenced DNA samples from Japanese sporadic ALS patients using an Ion Torrent PGM sequencer. We identified the known ALS pathogenic variants and predicted the functional properties of novel non-synonymous variants in silico. These variants were confirmed by Sanger sequencing. Known pathogenic variants were identified 14 (3.0%) of the 469 sporadic ALS patients. Thirty-two sporadic ALS patients (6.8%) harbored one or two novel non-synonymous variants of ALS-related genes that might be deleterious. This study reports the first extensive genetic screening of Japanese ALS patients. These findings are useful for developing genetic screening and counseling strategies for such patients.
