Parental perceptions of prenatal whole exome sequencing (PPPWES) study.

Participants' experience with exome sequence was similar to other prenatal genetic diagnostic tests, except for the longer wait time for results. When probed with hypothetical scenarios, participants desired more results than were provided in the study, including uncertain results that might diagnose the fetal condition. This highlights the need for specialized prenatal genetic counseling to have nuanced discussions of multiple dimensions of uncertainty with implementation of prenatal WES.
