Labcorp Genetics (formerly Invitae), Labcorp RCV001049897 SCV001213971 uncertain significance Ataxia-telangiectasia syndrome 2021-09-09 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. 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 threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with threonine at codon 2054 of the ATM protein (p.Ala2054Thr). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and threonine.
