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]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM5: Other missense variant is known to change same aminoacid residue: Variant chr8-11755064-A-G is described in Lovd as [Pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.764
• BS2: High AC in GnomAdExome4 at 8 AD gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 310 of the GATA4 protein (p.Met310Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GATA4-related conditions. ClinVar contains an entry for this variant (Variation ID: 1029406). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GATA4 protein function with a positive predictive value of 80%. This variant disrupts the p.Met310 amino acid residue in GATA4. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 20347099). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. -

PreventionGenetics, part of Exact Sciences

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The GATA4 c.928A>T variant is predicted to result in the amino acid substitution p.Met310Leu. This variant has not been reported in the literature in individuals with GATA4-related disorders. This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. An alternative variant affecting the same amino acid (p.Me310Thr) has been reported in a family with atrial septal defect (Bu et al. 2021. PubMed ID: 33413087). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
