Utility of Whole Genome Sequencing in Fetuses With Abnormal Ultrasound Findings

NCT07606989 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 1000

Last updated 2026-05-26

No results posted yet for this study

Summary

The goal of this observational study is to learn if whole-genome sequencing (WGS) can help find the genetic cause in fetuses with structural abnormalities that remain unexplained after standard genetic testing (such as karyotyping, chromosomal microarray, or whole-exome sequencing). It will also learn how WGS results may affect pregnancy management and family decision-making.

The main questions it aims to answer are:

How often does WGS identify a genetic cause in these fetuses? Does WGS find more genetic causes compared to standard genetic tests? Can combining WGS with other molecular analyses help discover new disease genes or pathways? Researchers will compare WGS results to results from standard genetic tests to see if WGS finds more genetic causes.

Participants are pregnant women whose fetuses have structural abnormalities seen on ultrasound or MRI, with negative results from routine genetic testing. Participants will:

Undergo an invasive procedure (such as amniocentesis) or provide postnatal samples as part of their regular medical care Allow the use of leftover samples for WGS and additional molecular studies Be followed until after delivery to collect information on pregnancy outcomes and neonatal health
