Frequent chromosomal translocations induced by DNA double-strand breaks

The faithful repair of DNA damage such as chromosomal double-strand breaks (DSBs) is crucial for genomic integrity. Aberrant repair of these lesions can result in chromosomal rearrangements, including translocations, which are associated with numerous tumours. Models predict that some translocations arise from DSB-induced recombination in differentiating lymphoid cell types or from aberrant repair of DNA damage induced by irradiation or other...
