Correction to: Leukemia (2007) 21, 584–586. doi:10.1038/sj.leu.2404507

Owing to a typesetting error, on page 1, second paragraph, the number ‘6’ was omitted in error, and this should have read ETV6/RUNX1+ instead of ETV/RUNX1+.

The Publisher would like to apologize for any inconvenience this may have caused.
