Objective
Expert prenatal focused gene‐disease curation is necessary to accurately inform clinical care in the setting of rapidly expanding prenatal genomic sequencing.
Methods
An international Prenatal Gene Curation Expert Panel assembled and systematically reviewed genes asserted to be associated with prenatal hydrops, stillbirth, or severe anomalies using the ClinGen framework.
Results
The ClinGen Prenatal GCEP published evidence summaries for 63 disease relationships involving 61 genes with unique and clinically severe prenatally observed fetal phenotypes.
Conclusion
The ClinGen Prenatal GCEP work addresses a gap in genomic medicine by deepening our understanding of lethal and severe prenatal phenotypes, while supporting accurate diagnosis, counseling, and future treatment strategies in prenatal care.
