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]

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. ClinVar contains an entry for this variant (Variation ID: 1503989). This variant has not been reported in the literature in individuals affected with GATA6-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces alanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 21 of the GATA6 protein (p.Ala21Ser). -
