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 c.1366C>T (p.R456C) alteration is located in exon 4 (coding exon 3) of the GATA6 gene. This alteration results from a C to T substitution at nucleotide position 1366, causing the arginine (R) at amino acid position 456 to be replaced by a cysteine (C). The GATA6 c.1366C>T alteration was flagged as a low confidence call in the Genome Aggregation Database (gnomAD). This variant has been determined to be the result of a de novo mutation in multiple individuals with features consistent with GATA6-related pancreatic agenesis and congenital heart defects (Allen, 2011; Yu, 2014). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic. -
