Response to Comment on "Reintroduction of the archaic variant of NOVA1 in cortical organoids alters neurodevelopment".

Maricic et al. performed an undisclosed in silico–only whole-exome sequencing analysis of our data and found genomic alterations previously undetected in some clones. Some of the predicted alterations, if true, could change the original genotype of the clones. We failed to experimentally validate all but one of these genomic alterations, which did not affect our previous results or data interpretation.
