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

DNA sequence analysis of the GATA2 gene demonstrated a sequence change, c.1367C>T, in exon 6 that results in an amino acid change, p.Pro456Leu. This sequence change does not appear to have been previously described in patients with GATA2-related disorders and has been described in the gnomAD database with an overall low population frequency of 0.0020% (dbSNP rs372912472). The p.Pro456Leu change affects a highly conserved amino acid residue located in a domain of the GATA2 protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Pro456Leu substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Pro456Leu change remains unknown at this time. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 456 of the GATA2 protein (p.Pro456Leu). This variant is present in population databases (rs372912472, gnomAD 0.01%). 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: 404068). 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) indicates that this missense variant is expected to disrupt GATA2 protein function with a positive predictive value of 95%. 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. -

Ambry Genetics

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
