Ambry Genetics | RCV000564180 | SCV000667986 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-08-30 | criteria provided, single submitter | clinical testing | The p.R3008G variant (also known as c.9022C>G), located in coding exon 62 of the ATM gene, results from a C to G substitution at nucleotide position 9022. The arginine at codon 3008 is replaced by glycine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV001210907 | SCV001382419 | likely pathogenic | Ataxia-telangiectasia syndrome | 2023-06-28 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Arg3008 amino acid residue in ATM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 9872980, 10817650, 12552566, 15101044, 18573109, 30549301). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. ClinVar contains an entry for this variant (Variation ID: 482635). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 3008 of the ATM protein (p.Arg3008Gly). |
