Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM2PP3
The NM_032638.5(GATA2):c.142T>C(p.Phe48Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,460,478 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. F48I) has been classified as Uncertain significance.

This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 48 of the GATA2 protein (p.Phe48Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with GATA2-related conditions (PMID: 34387894). ClinVar contains an entry for this variant (Variation ID: 1038088). 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. -
