Labcorp Genetics (formerly Invitae), Labcorp RCV002843737 SCV003220738 uncertain significance Hyper-IgE recurrent infection syndrome 1, autosomal dominant; STAT3 gain of function 2022-07-11 criteria provided, single submitter clinical testing 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 STAT3 protein function. This variant has not been reported in the literature in individuals affected with STAT3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 140 of the STAT3 protein (p.Lys140Asn).
