Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_032638.5(GATA2):c.682C>T(p.Pro228Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,858 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. P228L) has been classified as Uncertain significance.

Inborn genetic diseases    Uncertain:1 
The c.682C>T (p.P228S) alteration is located in exon 3 (coding exon 2) of the GATA2 gene. This alteration results from a C to T substitution at nucleotide position 682, causing the proline (P) at amino acid position 228 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections    Uncertain:1 
This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 228 of the GATA2 protein (p.Pro228Ser). This variant is present in population databases (rs375298899, gnomAD 0.0009%). 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: 1319420). 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 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. -
