Labcorp Genetics (formerly Invitae), Labcorp RCV003508300 SCV004267974 uncertain significance DiGeorge syndrome 2023-01-13 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals affected with TBX1-related conditions. 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 TBX1 protein function. This variant is present in population databases (rs533732094, gnomAD 0.006%). This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 245 of the TBX1 protein (p.Tyr245Ser).
