Correction to: Nature Genetics https://doi.org/10.1038/s41588-018-0311-9, published online 7 January 2019.

In the version of this article initially published, in the phase 3 meta-analysis, the UK Biobank results were overweighed with a slightly larger (5%) N, thus resulting in a minimal underestimation of effect sizes and in P values marginally less significant than their actual values. Because the differences were on the order of the ninth decimal, there is no notable effect on the results or the conclusions drawn. The summary statistics have been updated accordingly at https://ctg.cncr.nl/software/summary_statistics. The Data availability statement has been updated to include the new URL in the HTML and PDF versions of the article.
