Gestational age between 11+0 and 32+0 weeks, with ultrasound or MRI indicating a definite structural malformation in the fetus (may be with or without soft marker abnormalities) requiring prenatal diagnosis (see Appendices 1 and 2). Fetal developmental abnormalities include those of the central nervous system, cardiovascular system, craniofacial\u002Fneck region, chest\u002Fmediastinum, abdomen\u002Fdigestive tract, urinary system, skeletal system\u002Flimbs, and systemic abnormalities such as fetal hydrops, abnormally thickened placenta with hydrops, and severe growth restriction. Criteria for ultrasound soft markers and structural malformations are provided in the appendices.\n4. Planned to undergo at least one invasive or postnatal procedure for genetic diagnosis, and consent to the use of residual diagnostic samples for research testing.\n5. Signed unified informed consent form, agreement to follow-up, and consent for storage and submission of samples and data according to the protocol.\n\nExclusion Criteria:\n\n1. Age \\\u003C 18 years or individuals lacking full capacity for civil conduct.\n2. Twin or multiple pregnancies.\n3. Known parental or familial carrier status of a pathogenic variant highly consistent with the current fetal phenotype, where testing is planned only for targeted confirmation.\n4. Refusal to consent to the storage and use of samples and data for this study.\n5. Other conditions deemed unsuitable for participation in this study by the investigator.","FEMALE","18 Years",{"count":85,"type":86},1000,"ESTIMATED","OBSERVATIONAL","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.\n\nThe main questions it aims to answer are:\n\nHow 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.\n\nParticipants are pregnant women whose fetuses have structural abnormalities seen on ultrasound or MRI, with negative results from routine genetic testing. Participants will:\n\nUndergo 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",[90,91],"Prenatal Diagnosis","Fetal Diseases","2026-05-20",{"date":94,"type":95},"2026-05-26","ACTUAL",{"date":97,"type":95},"2026-03-12",{"date":99,"type":86},"2028-03-12",{"name":5,"class":6},4]
