Correction to: Nature https://doi.org/10.1038/s41586-020-2901-9 Published online 28 October 2020

In the version of the article initially published, we mistakenly provided information in Supplementary Table 1 for two healthy control samples that were not used in the study. Supplementary Table 1 has been corrected to include the correct information for the three healthy controls, which included two previously published datasets (GSM4462413 and GSM4462414).
