Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 2P and 6B. PM2BP4_ModerateBS2
The NM_032638.5(GATA2):c.1286G>A(p.Ser429Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00000342 in 1,461,892 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S429T) has been classified as Likely benign.

Inborn genetic diseases Uncertain:1
The p.S429N variant (also known as c.1286G>A), located in coding exon 5 of the GATA2 gene, results from a G to A substitution at nucleotide position 1286. The serine at codon 429 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections Uncertain:1
This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 429 of the GATA2 protein (p.Ser429Asn). This variant is not present in population databases (gnomAD no frequency). 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: 854262). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GATA2 protein function. 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. -
