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 was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.068621635).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000022 (32/1456410) while in subpopulation EAS AF = 0.000785 (31/39466). AF 95% confidence interval is 0.000568. There are 0 homozygotes in GnomAdExome4. There are 15 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High AC in GnomAdExome4 at 32 AD gene.

This variant has not been reported in the literature but is present in the Genome Aggregation Database (Highest reported MAF 0.1% (20/17588) (https://gnomad.broadinstitute.org/variant/3-128205667-C-A?dataset=gnomad_r2_1). This variant is present in ClinVar (Variation ID:472452). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
