The authors regret that, during the process of data collation prior to publication, the β-actin blotting of the Hbb-b1 sample in Fig. 9 E (left panel) was erroneously replicated from the β-actin blotting of the Hba-a2 sample in Fig. 8 H. The figure’s source data file is correct, and this error does not alter the findings in this article. The original and corrected figures are shown here.

The error appears in print and in PDFs downloaded before March 28, 2025.
