Correction to: Leukemia (2013) 27, 2056–2061;doi:10.1038/leu.2013.166

Since the publication of this article, the authors have noticed an omission in the Acknowledgements section, namely that the following had not been included: Asociación Española Contra el Cáncer (AECC; GCB120981SAN), Spain.

This has now been added to the Acknowledgements, and the corrected article appears in this issue. The html and online pdf versions have also been rectified, and now carry the correct paper.

The authors would like to apologise for any inconvenience this may have caused.
