Labcorp Genetics (formerly Invitae), Labcorp RCV003821640 SCV004626794 uncertain significance Treacher Collins syndrome 1 2022-11-14 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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. This variant has not been reported in the literature in individuals affected with TCOF1-related conditions. This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 264 of the TCOF1 protein (p.Lys264Arg). This variant is not present in population databases (gnomAD no frequency).
