Genes affected
GATA2 (HGNC:4171): (GATA binding protein 2) This gene encodes a member of the GATA family of zinc-finger transcription factors that are named for the consensus nucleotide sequence they bind in the promoter regions of target genes. The encoded protein plays an essential role in regulating transcription of genes involved in the development and proliferation of hematopoietic and endocrine cell lineages. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Mar 2009]

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

The GATA2 c.176A>G; p.Tyr59Cys variant (rs140047487), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 472450). This variant is found in the general population with an overall allele frequency of 0.001% (3/243,818 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is deleterious (REVEL: 0.947). Due to limited information, the clinical significance of this variant is uncertain at this time. -

Inborn genetic diseases Uncertain:1
Dec 16, 2024
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Y59C variant (also known as c.176A>G), located in coding exon 1 of the GATA2 gene, results from an A to G substitution at nucleotide position 176. The tyrosine at codon 59 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 59 of the GATA2 protein (p.Tyr59Cys). This variant is present in population databases (rs140047487, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with GATA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 472450). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GATA2 protein function. 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. -
