Variant summary
Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2
The NM_032638.5(GATA2):c.829A>G(p.Ser277Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000136 in 1,613,988 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. S277N) has been classified as Uncertain significance.

Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections Uncertain:1
This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 277 of the GATA2 protein (p.Ser277Gly). This variant is present in population databases (rs141800945, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with GATA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 435283). 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 not expected to disrupt GATA2 protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

- -
Inborn genetic diseases Benign:1
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
