In the version of this article initially published, there were inconsistences, where in the Methods “AF collection and isolation of the viable cell fraction” paragraph, the first sentence, now reading “AF samples (amniocenteses and amniodrainages) were collected from UCLH FMU and UZ Leuven as part of standard patient clinical care”, was initially preceded by “Euploid,” though the sample contained two chromosomal abnormalities; and in Supplementary Table 1, where for sample code HO680, the sex was listed as female following prenatal clinical data, whereas the sample was identified and processed in further analysis as male. The changes have been made in Supplementary Table 1 and in the HTML and PDF versions of the article.
