Correction to: Nature Biotechnology https://doi.org/10.1038/s41587-021-01088-y, published online 7 October 2021.

In the version of this article initially published, there was an error in the description of Omega’s engineered proteins, found in the 16th paragraph, first sentence. In the sentence now reading “Once an IGD and the genes it houses have been associated with a disorder, Omega researchers generate what they call ‘Omega Epigenomic Controllers (OECs)’,” the term “EpiZips” has been replaced by “Omega Epigenomic Controllers (OECs).” Similarly, in the third sentence of the same paragraph, “OECs” replaced “EpiZip” in the sentence now reading “To deliver the treatment, the researchers encapsulate mRNA transcripts within lipid nanoparticles; the mRNA is translated into the OECs after being taken up by the targeted cells.”

The errors have been corrected in the online version of the article.
