Correction to: Nature Genetics https://doi.org/10.1038/s41588-026-02539-5, published online 30 March 2026. In the version of the article initially published, in Fig. 5a, the arrow at position 52 from “G” to “A” was missing. In Fig. 5b, the arrow at position 8 from “C” to “U” was missing, the “80” label at position 90 should have read “90”, and the “1,160” label at position 160 should have read “160”. These corrections have been made to the HTML and PDF versions of the article.
