RCV001035824 | SCV001199162 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-08-09 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 602 of the ATM protein (p.Asn602Asp). 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. 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The aspartic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 835022). |
Ambry Genetics | RCV002409361 | SCV002714810 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-04-11 | criteria provided, single submitter | clinical testing | The p.N602D variant (also known as c.1804A>G), located in coding exon 11 of the ATM gene, results from an A to G substitution at nucleotide position 1804. The asparagine at codon 602 is replaced by aspartic acid, an amino acid with highly similar properties. This amino acid position is not well conserved in available vertebrate species, and aspartic acid is the reference amino acid in other vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
