Correction to: Nature Reviews Disease Primers https://doi.org/10.1038/s41572-021-00298-7, published online 02 September 2021.

In the original version of this article, the European Reference Network for Rare Multisystemic Vascular Disease (VASCERN), HTAD Rare Disease Working Group was incorrectly included in the author list as an institutional author. In addition, the Montalcino Aortic Consortium (MAC), Houston, TX, USA was incorrectly listed as an affiliation. In the HTML and PDF versions of the article, this error has now been corrected, and the Acknowledgement section has been updated to clarify membership of the authors in these organizations.
