Genes affected
GATA6 (HGNC:4174): (GATA binding protein 6) This gene is a member of a small family of zinc finger transcription factors that play an important role in the regulation of cellular differentiation and organogenesis during vertebrate development. This gene is expressed during early embryogenesis and localizes to endo- and mesodermally derived cells during later embryogenesis and thereby plays an important role in gut, lung, and heart development. Mutations in this gene are associated with several congenital defects. [provided by RefSeq, Mar 2012]

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) -

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. -
