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]

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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. ClinVar contains an entry for this variant (Variation ID: 472912). This variant has not been reported in the literature in individuals affected with GATA6-related conditions. This variant is present in population databases (rs770405157, gnomAD 0.003%). This sequence change affects codon 505 of the GATA6 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the GATA6 protein. It affects a nucleotide within the consensus splice site. -
