Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 2972 of the ATM protein (p.Gln2972Arg). This variant is present in population databases (rs763773991, gnomAD 0.01%). This missense change has been observed in individual(s) with breast and/or ovarian cancer, Lynch syndrome (PMID: 25980754, 29470806). ClinVar contains an entry for this variant (Variation ID: 230424). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -

The missense variant p.Gln2972Arg in ATM (NM_000051.3) has been submitted to ClinVar as a Variant of Uncertain Significance, but no details are available for independent assessment. This variant was identified in 1/1010 individuals in a breast and/or ovarian cancer cohort in India (Singh J et al.). The p.Gln2972Arg variant is novel (not in any individuals) in 1000 Genomes. The amino acid change p.Gln2972Arg in ATM is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance. -

Collection Method:clinical testing

The p.Q2972R variant (also known as c.8915A>G), located in coding exon 61 of the ATM gene, results from an A to G substitution at nucleotide position 8915. The glutamine at codon 2972 is replaced by arginine, an amino acid with highly similar properties. This variant was observed in an individual with early onset-breast cancer amongst a cohort of 1781 non-Ashkenazi Jewish individuals undergoing BRCA1/2 gene testing based on a personal history of breast cancer (Tung N et al. Cancer, 2015 Jan;121:25-33). This variant was also observed in a study of 1010 unrelated Indian patients with breast and/or ovarian cancer (Singh J et al. Breast Cancer Res Treat, 2018 Jul;170:189-196). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -

This missense variant replaces glutamine with arginine at codon 2972 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 been reported in individuals affected with breast cancer and/or ovarian cancer (PMID: 25186627, 29470806), as well as in an individual suspected of having Lynch syndrome (PMID: 25980754). This variant has been identified in 3/251412 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. -
