Genes affected

GATA4 (HGNC:4173): (GATA binding protein 4) This gene encodes a member of the GATA family of zinc-finger transcription factors. Members of this family recognize the GATA motif which is present in the promoters of many genes. This protein is thought to regulate genes involved in embryogenesis and in myocardial differentiation and function, and is necessary for normal testicular development. Mutations in this gene have been associated with cardiac septal defects. Additionally, alterations in gene expression have been associated with several cancer types. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]

Collection Method:clinical testing

ClinVar contains an entry for this variant (Variation ID: 599008). This missense change has been observed in individual(s) with clinical features of GATA4-related conditions (PMID: 30755392). This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 32 of the GATA4 protein (p.Ala32Pro). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
