Description

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. 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 ZEB2 protein function. This variant has not been reported in the literature in individuals affected with ZEB2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.02%). This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 623 of the ZEB2 protein (p.Asn623Ser).
