| Ambry Genetics | RCV000571970 | SCV000672653 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-10 | criteria provided, single submitter | clinical testing | The p.E1146G variant (also known as c.3437A>G), located in coding exon 23 of the ATM gene, results from an A to G substitution at nucleotide position 3437. The glutamic acid at codon 1146 is replaced by glycine, an amino acid with similar properties. This amino acid position is well 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. |

RCV000685630 | SCV000813116 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-06-14 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 485189). 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 glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 1146 of the ATM protein (p.Glu1146Gly). 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 tolerated. 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. |
