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]

This sequence change replaces alanine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 19 of the GATA6 protein (p.Ala19Glu). This variant is present in population databases (rs758867858, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with GATA6-related conditions. ClinVar contains an entry for this variant (Variation ID: 2060220). 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 tolerated. 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. -
