Genes affected
GATA4 (HGNC:4173): (GATA binding protein 4) This gene encodes a member of the GATA family of zinc-finger transcription factors. Members of this family recognize the GATA motif which is present in the promoters of many genes. This protein is thought to regulate genes involved in embryogenesis and in myocardial differentiation and function, and is necessary for normal testicular development. Mutations in this gene have been associated with cardiac septal defects. Additionally, alterations in gene expression have been associated with several cancer types. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

The p.G21V variant (also known as c.62G>T), located in coding exon 1 of the GATA4 gene, results from a G to T substitution at nucleotide position 62. The glycine at codon 21 is replaced by valine, an amino acid with dissimilar properties. This alteration has been reported to segregate with atrial septal defect in two apparently unrelated families, and luciferase assay suggested that this alteration would result in reduced transcriptional activity in the experimental system (Liu XY et al. Int. J. Mol. Med., 2011 Jul;28:17-23). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
