Description

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 445 of the GATA2 protein (p.Pro445Leu). 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. 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 expected to disrupt 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.
