Labcorp Genetics (formerly Invitae), Labcorp RCV001316532 SCV001507158 uncertain significance Insulin-dependent diabetes mellitus secretory diarrhea syndrome 2023-11-10 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 170 of the FOXP3 protein (p.Thr170Ala). This variant is present in population databases (rs782694663, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with FOXP3-related conditions. ClinVar contains an entry for this variant (Variation ID: 1017386). 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 with a negative predictive value of 80%. 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.
