Ambry Genetics | RCV000571690 | SCV000665354 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-01-17 | criteria provided, single submitter | clinical testing | The p.K342R variant (also known as c.1025A>G), located in coding exon 7 of the ATM gene, results from an A to G substitution at nucleotide position 1025. The lysine at codon 342 is replaced by arginine, an amino acid with highly similar 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. |

RCV000792012 | SCV000931284 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-12-17 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 342 of the ATM protein (p.Lys342Arg). 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: 481154). 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. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (Invitae). 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. |
