Structure-forming CAG/CTG repeats interfere with gap repair to cause repeat expansions and chromosome breaks
Abstract Expanded CAG/CTG repeats are sites of DNA damage, leading to repeat length changes. Homologous recombination (HR) is one cause of repeat instability and we hypothesized that gap filling was a driver of repeat instability during HR. To test this, we developed an assay such that resection and...
