Correction to: Nature Genetics https://doi.org/10.1038/s41588-021-00970-4, published online 13 December 2021.

In the version of this article initially published, CIROP was defined as ciliated left–right organizer metallopeptide instead of ciliated left–right organizer metallopeptidase. Also, accession codes for the human CIROP cDNA (NM_001402427.1) and protein (NP_001389356.1) reference sequences have been added. In Fig. 1 and the text, MIM numbers were inserted that are now available for CIROP and C1orf127 genes, as well as for the disorder caused by CIROP mutations (HTX12). Finally, in the section ‘CIROP is mutated in human patients with recessive HTX’, the mutation p.Cys269Ser was incorrectly shown as in ‘p.Cys296Ser’. The amendments have been made in the HTML and PDF versions of the article.
