The original version of this Article contained an error in Fig. 2a, in which the RAD51, RAD54 and MERGE panels displaying representative images for BRD9 shRNA1 were from an incorrect sample. This has been corrected in both the PDF and HTML versions of the Article. The Source Data file has also been replaced to include the correct uncropped images for Fig. 2a.
