Mutations in the OPTN gene are well known to be associated with the development of glaucoma. Recently, unique variations in the same gene have been reported in familial and sporadic Japanese cases of amyotrophic lateral sclerosis (ALS). We set out to evaluate the frequency of OPTN mutations in a sample of our familial and sporadic ALS cohorts. All coding exons of the OPTN gene were amplified and sequenced in 95 unrelated familial ALS (FALS) and 95 sporadic ALS (SALS) cases of European descent. Two variants were newly identified in 2 individual FALS cases. Unique variations in the OPTN gene are rare in FALS cases and were not identified in any SALS patients, all of European descent.
