ABSTRACT
<p><b>OBJECTIVE</b>To assess the value of array-based comparative genomic hybridization (array-CGH) for analyzing tissues derived from spontaneous abortion and stillbirth.</p><p><b>METHODS</b>Agilent Human Genome CGH Microarray 4×44 K chip and Affymetrix Cytoscan 750 K Array were utilized to detect genome-wide copy number variations (CNV) in 43 fetuses with spontaneous abortion and stillbirth. All identified CNV were analyzed with references from Database of Genomic variants (DGV), database of DECIPHER, ISCA and OMIM, as well as comprehensive literature review to determine whether the identified CNVs were pathogenic. Parental DNA of two cases was also analyzed with the same arrays for pathogenic or unknown significant CNVs.</p><p><b>RESULTS</b>All of the 43 specimens were successfully analyzed. Clinically significant chromosomal aberrations were identified in 32 (74.4%) of the samples, which included 26 aneuploidies and 10 pathogenic CNV.</p><p><b>CONCLUSION</b>Array-CGH is a fast and effective method for analyzing tissues derived from spontaneous abortions and stillbirths which may be difficult to culture for karyotype analysis.</p>
