Abstract

Significance A GGGGCC expansion mutation located in intron 1 of chromosome 9 ORF 72 ( C9ORF72 ) was recently described as a common cause of familial amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD). We show that this single mutation results in the accumulation of sense and antisense RNA foci plus six expansion proteins expressed by repeat-associated non-ATG (RAN) translation. RNAs accumulate in nuclear foci and the RAN proteins form cytoplasmic aggregates in neurons that often cluster in affected brain regions. These results indicate that bidirectional transcription and RAN translation are fundamental pathologic features of C9ORF72 ALS/FTD. Additionally these data have broad implications that change our understanding of how microsatellite expansion mutations are expressed in patient cells and how they cause disease.
