Labcorp Genetics (formerly Invitae), Labcorp RCV003624210 SCV004520521 uncertain significance Insulin-dependent diabetes mellitus secretory diarrhea syndrome 2023-10-15 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 203 of the FOXP3 protein (p.Gly203Arg). This variant is present in population databases (rs782259487, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with FOXP3-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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on FOXP3 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.
