Correction to: Nature Genetics https://doi.org/10.1038/s41588-020-0684-4, published online 14 September 2020.

In the version of this article initially published, in the second sentence of the Abstract, ‘independent association signals for 459 cell traits at 69 loci (52 of them novel)’ should have read ‘independent association signals for 459 cell traits at 70 loci (53 of them novel)’ to match the correct values in the main text. The error has been corrected in the HTML and PDF versions of the article.
