In Figure 3E of the original article, the authors showed a western blot of different Ba/F3 cell lines expressing various HER2 exon 20 mutations. It was recently brought to the authors’ attention that there was an extra lane on the western blot and that the labels on the blot were unclearly labeled. The unintentional error was that the last lane of the western blot for HER2 (top row) contained a positive control cell line, H1781, with known expression of HER2 that was not cropped from the image, and the labels were shifted incorrectly. This error has now been corrected in the article online. While this correction does not affect the findings or the conclusions of the study, the authors would like to apologize for this error and any confusion that it may have caused for readers.
