Structurally polymorphic C9orf72 hexanucleotide repeats cause an impairment in transcriptional processivity and lead to accumulation of truncated repeat-containing transcripts that bind to specific ribonucleoproteins, such as nucleolin, in a conformation-dependent manner resulting in nucleolar stress and C9orf72-linked pathology in amyotrophic lateral sclerosis and frontotemporal dementia.
