Atrioventricular septal defect 4 Uncertain:1
This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a GATA4-related disease. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This sequence change replaces glycine with serine at codon 242 of the GATA4 protein (p.Gly242Ser). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and serine. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Cardiovascular phenotype Uncertain:1
The c.724G>A (p.G242S) alteration is located in exon 3 (coding exon 2) of the GATA4 gene. This alteration results from a G to A substitution at nucleotide position 724, causing the glycine (G) at amino acid position 242 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
