Correction to: Nature Chemical Biology, published online 23 December 2019

In the version of this article originally published, the x-axis labels of Fig. 2g and 2h were switched. The x-axis label of 2g should read ‘GAPDH-EGFP’ and that of 2h should read ‘Lamin A/C-EGFP’. Additionally, the labels for genes AAVS1 and CCR5 in Fig. 2c should be italicized. The errors have been corrected in the HTML and PDF versions of the paper.
