Correction to: Gene Therapy (2013) 20, 450–459; doi:10.1038/gt.2012.101; published online 10 January 2013

Since the online publication of this article, the following errors have been identified.

In Figure 2b, the black bars indicate AAV9 (101-IC and 102-IC) and the white bars indicate AAV2.5 (103-IC and 104-IC). Figure 2a was labeled correctly. In Figure 5, panels F and G were mislabeled: panel F should be spleen and panel G should be liver. Similarly, in Supplementary Figure 4, panel E should be spleen and panel F should be liver.

The corrected article appears in this issue, and the html and PDF versions online have also been amended.

The authors would like to apologize for these errors.
