Uterine leiomyoma confounding a noninvasive prenatal test result

What's already known about this topic? The noninvasive prenatal testing from maternal blood can be confounded by maternal conditions that lead to structural variants/copy number variations in the genome. What does this study add? This study provides further evidence that the grossly ‘abnormal’ and ‘non‐reportable’ noninvasive prenatal testing result due to global genomic changes was attributable to a maternal uterine leiomyoma, in an otherwise normal fetus. The possibility of such adventitious findings is something about which physicians ordering noninvasive prenatal testing for their patients may want to offer pre‐test counseling.
