RCV000799071 | SCV000938718 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-10-27 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 2730 of the ATM protein (p.Gln2730Arg). This variant is present in population databases (rs762154857, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 645055). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant disrupts the p.Gln2730 amino acid residue in ATM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16189143, 19431188, 22869595). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. |
