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 c.1020G>A variant (also known as p.S340S), located in coding exon 4 of the GATA2 gene, results from a G to A substitution at nucleotide position 1020. This nucleotide substitution does not change the at codon 340. This nucleotide position is not well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will result in the creation or strengthening of a novel splice acceptor site. Based on the available evidence, the clinical significance of this variant remains unclear. -
