Abstract
Noninvasive prenatal screening with cell-free DNA is now considered a first-line screening for common aneuploidies. Advancements in existing laboratory techniques now allow to interrogate the entirety of the fetal genome, and many commercial laboratories have expanded their screening panels to include screening for rare autosomal aneuploidies and copy number variants. Here, we review the currently available data on the performance of fetal cell-free DNA to detect rare autosomal aneuploidies and copy number variants that are associated with clinically significant microdeletion and microduplication syndromes and the current position of medical societies on routine screening for these syndromes.
期刊介绍:
Each issue of Clinical Obstetrics and Gynecology is a complete symposium on one or two timely topics of interest in obstetrics and gynecology. For each quarterly issue, two prominent guest editors solicit contributions on key clinical topics of interest to practicing physicians. Procedures, current clinical problems, medical and surgical treatments, and effective diagnostic aids are all carefully reviewed in original articles. The result is an instructive resource that dispenses trustworthy clinical guidance that enhances your understanding of key areas of your practice.
