Labcorp Genetics (formerly Invitae), Labcorp RCV002780793 SCV003019743 uncertain significance Insulin-dependent diabetes mellitus secretory diarrhea syndrome 2021-08-31 criteria provided, single submitter clinical testing This sequence change replaces alanine with valine at codon 284 of the FOXP3 protein (p.Ala284Val). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and valine. This variant is not present in population databases (ExAC no frequency). 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) performed at Invitae indicates that this missense variant is not expected to disrupt 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.
