Variant summary

Our verdict is Pathogenic. The variant received 24 ACMG points: 24P and 0B. PS1_Very_Strong PM1 PM2 PP3_Strong PP5_Very_Strong

The NM_032638.5(GATA2):​c.1113C>G​(p.Asn371Lys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Synonymous variant affecting the same amino acid position (i.e. N371N) has been classified as Likely benign.

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

Our verdict: Pathogenic. The variant received 24 ACMG points.

• PS1: Transcript NM_032638.5 (GATA2) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.
• PM1: In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 10 uncertain in NM_032638.5
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.988
• PP5: Variant 3-128481849-G-C is Pathogenic according to our data. Variant chr3-128481849-G-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1184162.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 371 of the GATA2 protein (p.Asn371Lys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with GATA2-related conditions and/or myelodysplastic syndrome (PMID: 21670465, 24077845, 26702063; Invitae). ClinVar contains an entry for this variant (Variation ID: 1184162). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GATA2 protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
