Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_032638.5(GATA2):c.682C>A(p.Pro228Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,614,050 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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.

Deafness-lymphedema-leukemia syndrome;C3280030:Monocytopenia with susceptibility to infections    Uncertain:1 
This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 228 of the GATA2 protein (p.Pro228Thr). 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: 404075). 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) has been performed 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. -
