Genes affected
GATA5 (HGNC:15802): (GATA binding protein 5) The protein encoded by this gene is a transcription factor that contains two GATA-type zinc fingers. The encoded protein is known to bind to hepatocyte nuclear factor-1alpha (HNF-1alpha), and this interaction is essential for cooperative activation of the intestinal lactase-phlorizin hydrolase promoter. In other organisms, similar proteins may be involved in the establishment of cardiac smooth muscle cell diversity. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1806815). This variant has not been reported in the literature in individuals affected with GATA5-related conditions. This variant is present in population databases (rs782198035, gnomAD 0.004%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 393 of the GATA5 protein (p.Ala393Val). -

Review Status: no assertion criteria provided
Collection Method: clinical testing

The GATA5 c.1178C>T variant is predicted to result in the amino acid substitution p.Ala393Val. This variant has been reported in one family in a study of intellectual disability, but no clinical details were provided (Table S3, Harripaul et al. 2017. PubMed ID: 28397838). This variant is reported in 0.0036% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/20-61039908-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
