Abstract:
OBJECTIVETo explore the genetic etiology for fetuses featuring intrauterine growth anomalies using array-based comparative genomic hybridization (aCGH).
METHODSForty-nine fetuses were enrolled in this study. Genomic DNA of the abortive tissues was analyzed with aCGH.
RESULTSFourteen (28.6%) samples were found with chromosomal aberrations, which included 8 chromosomal aneuploidies and 6 micro-aberrations (4 with known clinical pathogenecity and 2 with unknown clinical significance).
CONCLUSIONNumerical and structural chromosomal aberrations underlie a significant proportion of fetal growth anomalies. aCGH has provided an effective method for delineating their genetic cause.
