				 Objective: To report the molecular findings of 89 fetuses with prenatal ultrasound diagnosis of congenital heart disease (CHD) and a normal karyotype through next-generation sequencing (NGS) in an attempt to improve our understanding of submicroscopic abnormalities present in malformed fetuses.
Method: High-throughput NGS was carried out in fetal cord blood samples. All potential cytogenetic alterations detected on NGS platforms were matched against the known copy number variant (CNV) database.
Results: A total of 204 CNVs were identified in the entire population of 89 fetuses with CHD. Eleven cases had no deletions or duplications, five cases (5.6%) had pathogenic CNVs, 13 cases had CNVs that were likely to be pathogenic, 42 cases had CNVs of uncertain significance, and 18 cases had benign and/or likely benign CNVs.
