Color Diagnostics, LLC DBA Color Health RCV000583109 SCV000687417 uncertain significance Hereditary cancer-predisposing syndrome 2023-12-05 criteria provided, single submitter clinical testing This missense variant replaces isoleucine with valine at codon 931 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 been identified in 1/251432 chromosomes 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV000821489 SCV000962247 uncertain significance Ataxia-telangiectasia syndrome 2023-11-01 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 931 of the ATM protein (p.Ile931Val). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 490492). 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 valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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 RCV000583109 SCV002746122 uncertain significance Hereditary cancer-predisposing syndrome 2021-03-16 criteria provided, single submitter clinical testing The p.I931V variant (also known as c.2791A>G), located in coding exon 17 of the ATM gene, results from an A to G substitution at nucleotide position 2791. The isoleucine at codon 931 is replaced by valine, an amino acid with highly similar properties. This amino acid position is not 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.
