Correction to: Nature Genetics, published online 29 March 2019.

In the version of this article initially published, in the legend to Fig. 4, the descriptions of panels d and e were switched, although the figure itself is labeled correctly; panel d shows data for British individuals in the UKBB, and panel e shows data for Japanese individuals in the BBJ. In addition, the copyright line read ‘The Author(s), under exclusive licence to Springer Nature America, Inc.’ but should have read ‘Springer Nature America, Inc.’ The errors have been corrected in the HTML and PDF versions of the article.
