Ambry Genetics RCV002376234 SCV002683994 uncertain significance Hereditary cancer-predisposing syndrome 2015-10-20 criteria provided, single submitter clinical testing The p.D2987V variant (also known as c.8960A>T), located in coding exon 61 of the ATM gene, results from an A to T substitution at nucleotide position 8960. The aspartic acid at codon 2987 is replaced by valine, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6499 samples (12998 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.002% (greater than 66000 alleles tested) in our clinical cohort. 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 p.D2987V remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003108065 SCV003783833 uncertain significance Ataxia-telangiectasia syndrome 2023-11-21 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 2987 of the ATM protein (p.Asp2987Val). 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: 1765263). 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.
