Ambry Genetics | RCV002373459 | SCV002684163 | uncertain significance | Hereditary cancer-predisposing syndrome | 2020-12-22 | criteria provided, single submitter | clinical testing | The p.E2904D variant (also known as c.8712G>C), located in coding exon 59 of the ATM gene, results from a G to C substitution at nucleotide position 8712. The glutamic acid at codon 2904 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV003100007 | SCV003468553 | likely pathogenic | Ataxia-telangiectasia syndrome | 2023-08-22 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 2904 of the ATM protein (p.Glu2904Asp). This variant is not present in population databases (gnomAD no frequency). 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: 1764420). 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.Glu2904 amino acid residue in ATM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8845835, 9244351). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. |
