Variant summary
Our verdict is Pathogenic. Variant got 18 ACMG points: 18P and 0B. PM1PM2PM5PP3_StrongPP5_Very_Strong
The NM_032638.5(GATA2):c.1081C>T(p.Arg361Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,200 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R361P) has been classified as Likely pathogenic.

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 24266605, 21892158, 26812071, 24077845, 27418648, 30521493, 26702063, 31413257, 30933029, 31309983, 23502222, 24227816, 34469508, 35603181, 34529785, Bello2024[abstract], 24345756, 34387894, Abellard2023[abstract], 27013649, 1714909, 28179282, 25879889, 32135276) -

Monocytopenia with susceptibility to infections Pathogenic:1
The variant is not observed in the gnomAD v2.1.1 dataset. Predicted Consequence/Location: Missense variant In silico tool predictions suggest damaging effect of the variant on gene or gene product [REVEL: 0.97 (>=0.6, sensitivity 0.68 and specificity 0.92); 3Cnet: 0.99 (>=0.6, sensitivity 0.72 and precision 0.9)]. Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000472431 /PMID: 23502222 /3billion dataset). Different missense changes at the same codon (p.Arg361Gly, p.Arg361His, p.Arg361Leu, p.Arg361Pro) have been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000029721, VCV000435282, VCV001184156 /PMID: 21892158, 24077845, 29724903, 34529785). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections Pathogenic:1
This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 361 of the GATA2 protein (p.Arg361Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of GATA2-related conditions (PMID: 23502222, 24077845, 24266605, 25879889, 26812071, 27418648, 32135276). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 472431). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt GATA2 protein function with a positive predictive value of 95%. This variant disrupts the p.Arg361 amino acid residue in GATA2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 21892158). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
Acute myeloid leukemia;C3279664:Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections;C3463824:Myelodysplastic syndrome Pathogenic:1
This variant has been reported in the literature in at least 7 individuals with a range of clinical features including myelodysplastic syndrome, various types of cytopenia, recurrent infection, and lymphedema (Hsu 2013 PMID: 23502222; Webb 2016 PMID: 26812071; Gardner 2019 PMID: 30933029; Shamriz 2022 PMID: 35603181), including at least once as a de novo variant (Simon 2020 PMID: 32135276); additionally, this variant was found to segregate in at least 3 family members who were apparently asymptomatic but showed similarly reduced cell counts as their symptomatic family members (Svobodova 2013 PMID: 25879889; Nováková 2016 PMID: 27013649). This variant is present in 1 total allele in the Genome Aggregation Database (Highest reported MAF: 0.02% [1/5180]; https://gnomad.broadinstitute.org/variant/3-128481881-G-A?dataset=gnomad_r3); please note, disease-causing variants may be present in control databases at low frequencies, reflective of the general population, incomplete penetrance, and/or variable expressivity. This variant is also present in ClinVar, with classifications ranging from likely pathogenic to pathogenic (Variation ID: 472431). Evolutionary conservation and computational predictive tools strongly suggest that this variant may impact the protein. In summary, this variant is classified as pathogenic. -
