RCV000586643 | SCV000694192 | uncertain significance | not provided | 2017-08-21 | criteria provided, single submitter | clinical testing | Variant summary: The ATM c.1901A>T (p.Glu634Val) variant involves the alteration of a conserved nucleotide. 2/3 in silico tools predict a benign outcome for this variant (SNPsandGO not captured due to low reliability index). This variant is absent in 119572 control chromosomes (ExAC). The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases/clinical diagnostic laboratories; nor evaluated for functional impact by in vivo/vitro studies. Because of the absence of clinical information and the lack of functional studies, the variant is classified as a variant of uncertain significance (VUS) until additional information becomes available. |

RCV001860116 | SCV002265994 | uncertain significance | Ataxia-telangiectasia syndrome | 2024-01-24 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 634 of the ATM protein (p.Glu634Val). 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: 495387). 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. |
| Ambry Genetics | RCV002413661 | SCV002721982 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-06-04 | criteria provided, single submitter | clinical testing | The p.E634V variant (also known as c.1901A>T), located in coding exon 12 of the ATM gene, results from an A to T substitution at nucleotide position 1901. The glutamic acid at codon 634 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is well conserved in 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. |
