Hexanucleotide repeat expansions in C9orf72 gene locus create double jeopardy, first by leading to DNA–RNA R-loops that spawn double-strand breaks and second by the synthesis of dipeptide repeats that hinder DNA repair. This two-pronged mechanism may explain neurodegeneration in amyotrophic lateral sclerosis and frontotemporal dementia.
