Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP3_Strong PP5

The NM_032638.5(GATA2):​c.1082G>A​(p.Arg361His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R361C) has been classified as Likely pathogenic.

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 11 ACMG points.

• PM1: In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 11 uncertain in NM_032638.5
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr3-128481881-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 472431.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.989
• PP5: Variant 3-128481880-C-T is Pathogenic according to our data. Variant chr3-128481880-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 1184156.We mark this variant Likely_pathogenic, oryginal submission is: [Conflicting_classifications_of_pathogenicity].

The c.1082G>A (p.R361H) alteration is located in exon 5 (coding exon 4) of the GATA2 gene. This alteration results from a G to A substitution at nucleotide position 1082, causing the arginine (R) at amino acid position 361 to be replaced by a histidine (H). This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This variant was reported in individuals with features consistent with GATA2 deficiency syndrome (Bluteau, 2018; Galera, 2018; Jung, 2018; McReynolds, 2019; Wlodarski, 2016; Zhang, 2015). This amino acid position is highly conserved in available vertebrate species. This missense alteration is located in a region that has a low rate of benign missense variation (Lek, 2016; Firth, 2009). This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as likely pathogenic. -
