Correction to: Nature Medicine, published online 24 January 2022.

In the version of this article initially published, reference 48 (Nurden P. et al. Br. J. Haematol 110, 704–714 (2000)) was incorrect; it should have been Berrou, E. et al. A mutation of the human EPHB2 gene leads to a major platelet functional defect. Blood 132, 2067–2077 (2018). Further, the Acknowledgements section omitted the statement “We also thank the CIQLE Laënnec-Centre d’Imagerie Quantitative Lyon-Est (France) for expert technical assistance with the electron microscopy studies, and we thank J. C. Bordet (Laboratoire d’Hémostase, Centre de Biologie Est, Hospices Civils de Lyon, Bron, France) for his expertise in transmission electron microscopy and image analysis.” The changes have been made to the HTML and PDF versions of the article.
