ABSTRACT
<p><b>OBJECTIVE</b>To provide prenatal diagnosis for a pregnant woman with a history of Williams-Beuren syndrome pregnancy.</p><p><b>METHODS</b>The karyotypes of the fetus and his parents were analyzed with routine G-banding. Their genomic DNA was also analyzed with array comparative genomic hybridization (aCGH).</p><p><b>RESULTS</b>No karyotypic abnormality was detected for the fetus and his parents. aCGH has identified a de novo 5.09 Mb deletion at 2p13.3-p12 in the fetus.</p><p><b>CONCLUSION</b>The 2p13.3-p12 microdeletion carried by the fetus was de novo. As it has involved dosage-sensitive genes SPR and DCTN1, the deletion is probably pathogenic.</p>
