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]

The p.R398W pathogenic mutation (also known as c.1192C>T), located in coding exon 5 of the GATA2 gene, results from a C to T substitution at nucleotide position 1192. The arginine at codon 398 is replaced by tryptophan, an amino acid with dissimilar properties. This mutation has been detected in multiple unrelated individuals with GATA2 deficiency syndrome (Dickinson RE et al. Blood, 2011 Sep;118:2656-8; Hsu AP et al. Blood, 2011 Sep;118:2653-5; Churpek JE et al. Blood, 2015 Nov;126:2484-90; Mardahl M et al. Br J Haematol, 2019 Aug;186:471-476; West RR et al. Blood Adv, 2022 Feb;6:793-807). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 398 of the GATA2 protein (p.Arg398Trp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with GATA2 deficiency (PMID: 21670465, 21765025). ClinVar contains an entry for this variant (Variation ID: 29709). 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%. Experimental studies have shown that this missense change affects GATA2 function (PMID: 29882021). For these reasons, this variant has been classified as Pathogenic. -
