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]

The GATA6 c.1320T>A variant is not predicted to result in an amino acid change (p.=). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0080% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/18-19761431-T-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
