| Ambry Genetics | RCV001026237 | SCV001188579 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-02-02 | criteria provided, single submitter | clinical testing | The p.Q2433L variant (also known as c.7298A>T), located in coding exon 48 of the ATM gene, results from an A to T substitution at nucleotide position 7298. The glutamine at codon 2433 is replaced by leucine, an amino acid with dissimilar 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. |

RCV001060104 | SCV001224766 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-11-27 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 2433 of the ATM protein (p.Gln2433Leu). 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: 826950). 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. |
