Abstract
To assess the value of combined chromosomal karyotyping and BACs-on-Beads(BoBs) assay for the prenatal diagnosis of high risk gravida from Ningbo. For 2779 women, results of conventional karyotyping analysis and BoBs assay were compared. For common aneuploidies involving chromosomes 13, 18, 21, X and Y, the two methods have yielded a concordance rate of 98.78%. Eight cases detected with microduplication by BoBs were missed by karyotyping analysis. On the other hand, 17 structural chromosomal abnormalities, 10 chimeras and 1 triploidy detected by karyotyping analysis were missed by BoBs. The BoBs technology has featured high throughput and rapidity, and can detect 9 microdeletion syndromes, which can improve the quality of prenatal diagnosis and provide an ideal complementary for conventional chromosomal karyotyping.
