Although both genetic and environmental factors are thought to be causative, the critical cause of this cluster has not been identified. C9orf72 is the most common genetic factor in both familial and sporadic C9orf72-related ALS in people of European ancestry, but it is rare among Japanese populations. However, a previous report revealed that the frequency of C9orf72-related ALS was significantly higher in the cluster area. We evaluated the proportion of C9orf72 hexanucleotide repeat expansions in 99 cases of ALS diagnosed in Wakayama Prefecture, including the cluster area, by using repeat-primed polymerase chain reaction and fluorescence fragment length analysis. We found that 2 of the 99 patients (0 % of those with familial ALS and 2.4 % of those with sporadic ALS) had hexanucleotide repeat expansions in C9orf72, and long-read sequencing revealed that these expansions were causative. No expansions were observed among 90 patients with Parkinson's disease or among 90 healthy controls. Haplotype analysis with long-read sequencing data revealed that the two patients with repeat expansions shared the common haplotype with that previously reported in Finnish patients with C9orf72-related ALS, which suggests a founder effect. C9orf72 was thought to be a rare causative gene in Japan, but this study revealed that it may be relatively common in Wakayama Prefecture.","subitem_description_language":"en"},{"subitem_description":"This work was supported by Japan Society for the Promotion of Science Grant-in-Aid (KAKENHI, grant numbers 18H02743, 21H04818,
