Comprehensive analysis of copy number variations in congenital heart defects Tunisian patients: chromosomal microarray analysis insights

2026Open accessUniversity of Sousse

Abstract

This study reinforces the clinical utility of CMA in detecting cryptic chromosomal abnormalities in syndromic CHD. The identified CNVs and gene candidates offer new insights into CHD genetic architecture and support CMA as a first-tier diagnostic tool. These findings highlight the contribution of rare, pathogenic CNVs in syndromic cases and suggest their integration into refined diagnostic and counseling strategies. Further functional studies are necessary to elucidate the roles of these candidates in cardiogenesis.
