Submissions by phenotype
not provided Uncertain:1
Identified in one family with atrial fibrillation and congenital heart defects (Tucker et al., 2017); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Published in vitro functional studies suggest this variant results in increased expression of GATA6 target genes, NPPA and aMHC (Tucker et al., 2017); however, additional studies are needed to clarify the effect of this variant in vivo; Identified in one family with atrial fibrillation and congenital heart defects (Tucker et al., 2017); This variant is associated with the following publications: (PMID: 27756709, 27825974) -
Atrioventricular septal defect 5 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 585 of the GATA6 protein (p.Arg585Leu). This variant is present in population databases (rs201707559, gnomAD 0.03%). This missense change has been observed in individual(s) with atrialfibrillation and septal defects (PMID: 27756709). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 582510). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects GATA6 function (PMID: 27756709). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
