Genetic counseling for fetal sex prediction by NIPT: Challenges and opportunities.

Non-invasive prenatal testing (NIPT) has grown in ubiquity in the last decade and is now endorsed by Society for Maternal Fetal Medicine and American College of Obstetricians and Gynecologists as a screening tool for aneuploidy in all patients. Past studies have demonstrated a tendency among obstetrics patients to focus on the ability of NIPT to predict fetal sex chromosomes; however, data on the experiences of genetic counselors (GCs) counseling on NIPT and fetal sex prediction are limited. This mixed-methods study aimed to explore how GCs counsel about NIPT and fetal sex prediction, as well as the use of gender-inclusive language in this setting.

Utility of noninvasive genome-wide screening: a prospective cohort of obstetric patients undergoing diagnostic testing.

Purpose: Copy-number variant (CNV) assessment is recommended for patients undergoing prenatal diagnostic testing. Noninvasive screening tests have not been extensively validated for CNV detection. The objective of this study was to compare the ability of genome-wide noninvasive prenatal screening (NIPS) to chromosomal microarray to detect clinically significant findings.
