This study looks at whether genome sequencing should be used more routinely during pregnancy, even when ultrasounds look normal. Genome sequencing can examine nearly all of a baby's genes and may find genetic conditions that standard tests do not detect. Researchers will compare this test with current prenatal testing to see if it provides helpful information for families and doctors. The study will also explore how parents decide what kinds of genetic information they want to receive and how this information affects their experience during pregnancy. The goal is to understand whether genome sequencing can be used in a way that is helpful, responsible, and supportive for families in the future.
This multicenter, observational cohort study will evaluate prenatal sequencing among pregnancies with no fetal structural anomalies recruited at university based medical centers and evaluated at the New York Genome Center. Pregnancies with no fetal structural anomalies and meeting eligibility criteria will be enrolled into the study.
The prenatal sequencing group will be used to determine the frequency of pathogenic, likely pathogenic, and uncertain genomic variants identifiable by sequencing and the relative yield of sequencing. The prenatal sequencing group will be evaluated to understand the psychosocial needs of pregnant couples. Mothers, fathers and infants will be followed through 1 year postpartum.
The main objective of this multi-center collaborative study is to evaluate genome sequencing as a prenatal diagnostic tool in pregnancies with no known structural anomalies. Specifically, the aims are as follows:
Aim 1: Determine in pregnancies with a normal finding on ultrasound imaging, the frequency and types of fetal and maternal genetic conditions identified by GS, which impact clinical care. The goal is to understand the scope of these conditions, explore appropriate reporting criteria in pregnancy, and the role of genetic conditions in maternal morbidity and mortality.
Aim 2: Determine parental attitudes, choices, and the impact of offering prenatal whole genome sequencing as a genetic diagnostic screen in pregnancies with normal ultrasound anatomy. Clinician and community perspectives on the utility of prenatal GS as a non-invasive tool will be evaluated.
Aim 3: Expand the infrastructure for the standardized collection of prenatal genotype and phenotype data that is required to maximize future interpretive algorithms.

| Genome Sequencing (GS) | Genetic | Genome sequencing (GS) is a genetic test that involves reading the genome to identify genetic changes (also known as "genetic variants") that can cause differences in human development and disease. |
| Measure | Description | Time Frame |
|---|---|---|
| Incremental Genomic Frequency | The incremental frequency of fetal genetic conditions identified and reported by genomic sequencing (GS) compared to those found by standard-of-care (SOC) testing, including pathogenic, likely pathogenic, or variant of uncertain significance (VUS) variants identified by sequencing and deemed reportable by the Variant Adjudication Committee | Baseline to 12 months postpartum. |
| Measure | Description | Time Frame |
|---|---|---|
| Frequency and type of pathogenic and likely pathogenic (P/LP) genomic findings by SOC and GS independently | Baseline to 12 months postpartum. | |

At the conclusion of the study, the final dataset will be prepared by Columbia and Broad for archiving and sharing.
Raw genomic data (CRAM/VF) and detailed phenotype information will be submitted to the RIFGC. Controlled access to this repository is governed by dbGaP authorization requests and supervised by the consortium. Raw data, when possible, are available through AnVIL. We will also utilize governance and standards including Clinical Laboratory Improvement Amendments, Health Insurance Portability and Accountability Act (HIPAA), Fast Healthcare Interoperability Resources (FHIR) Health Level 7 (HL7), United States Core Data for Interoperability (USCDI), and the National Center for Biotechnology Information (NCBI) MedGen.
