dc.description.abstractBackground Congenital heart disease (CHD) is the most prevalent developmental defect and principal cause of infant mortality and affects cardiac and large blood vessel structures in approximately 1% of live births worldwide. To date, numerous studies have related critical genetic dysfunctions to the pathogenesis of CHDs. However, the genetic basis underlying CHD remains largely unknown. In the present study, we investigated the association of nucleotide variations in coding and noncoding regions of the HAND1 gene with the risk of CHD. The HAND1 gene, encoding a helix-loop-helix transcription factor, is particularly relevant for mechanisms underlying CHD since it plays a significant role in heart development. Methods and results The genomic DNA of 150 unrelated pediatric patients with CHD was screened by PCR-SSCP and direct sequencing. Four novel and heterozygous missense mutations were identified in the first exon, with three causing amino acid substitutions (p.Val149Met, p.Tyr142His, and p.Leu146Met). In-silico analysis also indicated their deleterious impact on protein structure and function. In addition, we identified five novel nucleotide variants in the 3′UTR region (c.*461, c.*342, c.*529, c.*448, c.*593), potentially altering the target sites of miRNAs. These changes include the loss of certain target sites and the acquisition of new ones. Conclusions These findings confirm the phenotypic association between CHDs and HAND1 mutations and can pave the way for developing new preventive and therapeutic strategies.eng
