Correction to: Oncogene advance online publication, 24 November 2014; doi:10.1038/onc.2014.378

Following the online publication of this article, the authors have noticed a misspelt surname: S Hider should read S Haider.

There is also an addition to the acknowledgements to read ‘This study makes use of data generated by the Molecular Taxonomy of Breast Cancer International Consortium, which was funded by Cancer Research UK and the British Columbia Cancer Agency Branch’.

The corrected article appears in this issue. The authors would like to apologise for any inconvenience this may cause.
