Retraction to: Communications Biology https://doi.org/10.1038/s42003-021-02668-z, published online 11 October 2021.

The authors are retracting this Article as irregularities were found in the data that indicate the splicing of the U2AF2 exon 2 does not occur as reported in the Article. The irregularities call into question the conclusions and undermine our full confidence in the integrity of the study. The authors therefore wish to retract the Article.

All of the authors agree with the retraction.
