Accuracy of expanded noninvasive prenatal testing for maternal copy number variations: A comparative study with CNV-seq of maternal lymphocyte DNA

1 Jul 2024

Abstract excerpt

OBJECTIVE: To evaluate the accuracy of expanded noninvasive prenatal testing (NIPT) for maternal copy number variations. MATERIALS AND METHODS: Expanded NIPT was used to detect CNVs ≥2 Mb at a whole-genome scale. The threshold of maternal deletion was copy numbers (CN) ≤ 1.6, and the threshold of maternal duplication was CN ≥ 2.4. RESULTS: Of the 5440 pregnant women with successful expanded NIPT results, 28...
