Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease caused by the progressive degeneration of motor neurons. Recently, genetic variants in GLT8D1 and ARPP21 were associated with ALS in a cohort of European descent. A synergistic relationship was proposed between ALS associated variants in GLT8D1 and ARPP21. We aimed to determine the prevalence of genetic variation in GLT8D1 and ARPP21 in an Australian cohort of familial (n = 81) and sporadic ALS (n = 618) cases using whole-exome and whole-genome sequencing data. No novel mutations were identified in either gene, nor was there significant enrichment of protein-altering sequence variation among ALS cases. GLT8D1 and ARPP21 mutations are not a common cause of ALS in Australian familial and sporadic cohorts.
