PG - 808-814 LID - 10.3760/cma.j.issn.0529-567x.2019.12.004 [doi] AB - Objective: To evaluate the application of combinatorial probe anchor synthesis (cPAS)-based high-throughput low coverage whole genome sequencing in chromosomal aberration detection in spontaneous miscarriage. Methods: From September 2015 to May 2017, spontaneous miscarriage samples were collected from Inner Mongolia Maternal and Child Health Care Hospital. Those samples were further analyzed with two independent methods, fluorescence in situ hybridization (FISH) and low coverage whole genome sequencing on the BGISEQ-500 high-throughput platform. The performance of low coverage whole genome sequencing was assessed by comparing to FISH results. Results: In 595 spontaneous miscarried specimens, low coverage whole genome sequencing revealed 144 cases (24.2%, 144/595) chromosomal abnormalities, of which a subset of 137 cases (23.0%, 137/595) were detected as aneuploidies, 2 cases (0.3%, 2/595) as mosaicisms and 5 cases (0.8%, 5/595) as copy number variation (>/=5 Mb). Conclusion: cPAS-based high-throughput low coverage whole genome sequencing is a reliable method in detecting chromosomal aberrations inspontaneous abortion tissues, including chromosome aneuploidies, mosaicisms and copy number variation (>/=5 Mb).
