| Ambry Genetics | RCV001018935 | SCV001180232 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-06-08 | criteria provided, single submitter | clinical testing | The p.A3054P variant (also known as c.9160G>C), located in coding exon 62 of the ATM gene, results from a G to C substitution at nucleotide position 9160. The alanine at codon 3054 is replaced by proline, an amino acid with highly similar properties. This amino acid position is highly conserved through mammals but not in all available 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. |

RCV001367031 | SCV001563363 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-05-20 | criteria provided, single submitter | clinical testing | 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 proline 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: 823056). 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 alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 3054 of the ATM protein (p.Ala3054Pro). |

RCV001018935 | SCV004361948 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-11-06 | criteria provided, single submitter | clinical testing | This missense variant replaces alanine with proline at codon 3054 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with ATM-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
