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]

GATA4 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 8-11757012-G-T is Pathogenic according to our data. Variant chr8-11757012-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 967905.Status of the report is criteria_provided_single_submitter, 1 stars.

ClinVar contains an entry for this variant (Variation ID: 967905). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with GATA4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu359*) in the GATA4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GATA4 are known to be pathogenic (PMID: 12845333, 15235040). -
