Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2
The NM_032638.5(GATA2):c.748C>T(p.Pro250Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000929 in 1,614,048 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. P250A) has been classified as Benign.

Submissions by phenotype
Inborn genetic diseases Uncertain:1
The p.P250S variant (also known as c.748C>T), located in coding exon 2 of the GATA2 gene, results from a C to T substitution at nucleotide position 748. The proline at codon 250 is replaced by serine, an amino acid with similar properties. This amino acid position is highly 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 proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 250 of the GATA2 protein (p.Pro250Ser). This variant is present in population databases (rs78245253, 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: 472465). 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. -
