Application of array comparative genomic hybridization analysis for fetuses with growth anomalies / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the genetic etiology for fetuses featuring intrauterine growth anomalies using array-based comparative genomic hybridization (aCGH).</p><p><b>METHODS</b>Forty-nine fetuses were enrolled in this study. Genomic DNA of the abortive tissues was analyzed with aCGH.</p><p><b>RESULTS</b>Fourteen (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).</p><p><b>CONCLUSION</b>Numerical and structural chromosomal aberrations underlie a significant proportion of fetal growth anomalies. aCGH has provided an effective method for delineating their genetic cause.</p>
