Labcorp Genetics (formerly Invitae), Labcorp RCV000685242 SCV000812715 uncertain significance DiGeorge syndrome 2018-01-03 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with TBX1-related disease. While this variant is not present in population databases, the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change replaces glycine with glutamic acid at codon 390 of the TBX1 protein (p.Gly390Glu). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and glutamic acid. 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.
