Correction to: Nature Microbiology https://doi.org/10.1038/s41564-018-0334-0, published online 21 January 2019.

In the version of this Letter originally published, in the sentence beginning “The major driver role of DDX3X mutations...”, the citation “Fig. 2a–f” should have been “Fig. 2”. In addition, in the sentence beginning “Another finding of interest was the presence of identical driver mutations...”, the citation “Fig. 3a,b and Fig. 4” should have been “Fig. 3”. This has now been amended in all versions of the Letter.
