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.787G>A variant is predicted to result in the amino acid substitution p.Gly263Arg. To our knowledge, this variant has not been reported in the literature in association with disease. This variant has been reported in a study of cancer-susceptibility genes in a healthy, ancestrally diverse cohort (Table S1, Bodian et al. 2014. PubMed ID: 24728327) and is reported in 0.011% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-128204654-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.G263R variant (also known as c.787G>A), located in coding exon 2 of the GATA2 gene, results from a G to A substitution at nucleotide position 787. The glycine at codon 263 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
