ABSTRACT
OBJECTIVE:
Deleterious genetic variants comprise one cause of cardiac conotruncal defects (CTDs). Genes associated with CTDs are gradually being identified. In the present study, we aimed to explore the profile of genetic variants of CTD-associated genes in Chinese patients with non-syndromic CTDs.METHODS:
Thirty-nine CTD-related genes were selected after reviewing published articles in NCBI, HGMD, OMIM, and HPO. In total, 605 patients with non-syndromic CTDs and 300 healthy controls, all of Han ethnicity, were recruited. High-throughput targeted sequencing was used to detect genetic variants in the protein-coding regions of genes. We performed rigorous variant-level filtrations to identify potentially damaging variants (Dvars) using prediction programs including CADD, SIFT, PolyPhen-2, and MutationTaster.RESULT:
Dvars were detected in 66.7% (26/39) of the targeted CTD-associated genes. In total, 11.07% (67/605) of patients with non-syndromic CTDs were found to carry one or more Dvars in targeted CTD-associated genes. Dvars in FOXH1, TBX2, NFATC1, FOXC2, and FOXC1 were common in the CTD cohort (1.5% [9/605], 1.2% [7/605], 1.2% [7/605], 1% [6/605], and 0.5% [3/605], respectively).CONCLUSION:
Targeted exon sequencing is a cost-effective approach for the genetic diagnosis of CTDs. Our findings contribute to an understanding of the genetic architecture of non-syndromic CTDs.Palabras clave
