In Prenatal Testing, Genomics Sometimes Sees What Other Tests Can’t

A new kind of prenatal genetic testing can improve obstetricians' ability to diagnose the underlying causes of fetal anomalies found during prenatal ultrasounds. But the results require expert interpretation, according to a study by researchers at Columbia University Vagelos College of Physicians and Surgeons. The study was published in The Lancet.

The work, led by Ronald Wapner, MD, director of reproductive genetics at Columbia University’s Institute for Genomic Medicine (IGM) and vice chair of research in obstetrics and gynecology, and David Goldstein, Ph.D., director of the IGM, clarifies the utility and limitations of such tests.
