Mosaic Maternal UPD15 in a Newborn with Complex Heart Defect
Product Description:
We present a case of a newborn male with MCA, including congenital heart defect, diagnosed by our laboratory with Prader Willi syndrome (PWS) caused by mosaic maternal uniparental disomy 15 (UPD15) with concomitant low-level trisomy 15 resulting from an incomplete trisomy 15 rescue. This report highlights the ability of SNP array to identify UPD and the importance of understanding the underlying mechanisms of UPD to make accurate diagnosis, interpretation, and appropriate recommendations. This report also illustrates the value of using a combination of genetic tests in order to make the correct diagnosis in some patients.
