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]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 16 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.086625084 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.6, offset of 11, new splice context is: ccctcccattcggccgccAGaag. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 19, 2023 | This sequence change affects an acceptor splice site in intron 4 of the GATA2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in GATA2 are known to be pathogenic (PMID: 21670465, 23223431). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individuals with GATA2-related conditions (PMID: 21670465, 21765025, 26022708). ClinVar contains an entry for this variant (Variation ID: 29716). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. - |
