Labcorp Genetics (formerly Invitae), Labcorp RCV003625879 SCV004451999 uncertain significance Insulin-dependent diabetes mellitus secretory diarrhea syndrome 2023-04-06 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 FOXP3 protein function. This variant has not been reported in the literature in individuals affected with FOXP3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 140 of the FOXP3 protein (p.Val140Leu).
GeneDx RCV004765945 SCV005375939 uncertain significance not provided 2023-11-28 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
