In the version of this article initially published, due to a figure preparation error, the image shown in the upper-middle panel of Extended Data Fig. 2d for the Cflar KI dot plot was an inadvertent duplicate of the adjacent dot plot (wild-type). Due to the age of the article, the figure cannot be updated directly; the revised Extended Data Fig. 2, panel d, is available as Supplementary Information alongside this amendment. This amendment serves to update the article.
