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]
C11orf65 (HGNC:28519): (chromosome 11 open reading frame 65) Predicted to be involved in negative regulation of mitochondrial fission and negative regulation of protein targeting to mitochondrion. Predicted to be located in cytosol and mitochondrial outer membrane. [provided by Alliance of Genome Resources, Apr 2022]

Variant summary: ATM c.8737G>T (p.Asp2913Tyr) results in a non-conservative amino acid change located in the ATM, catalytic domain (IPR044107) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251460 control chromosomes (gnomAD). c.8737G>T has been reported in the literature in multiple homozygous and compound heterozygous individuals affected with Ataxia-Telangiectasia (e.g. Micol_2011, Jacquemin_2012). The variant has also been reported in individuals affected with breast and prostate cancer (e.g. Lu_2019, Dorling_2021, Karlsson_2021). These data indicate that the variant is very likely to be associated with disease. Experimental evidence evaluating an impact on protein function demonstrated that the variant results in reduced protein expression, while it alters subcellular localization and cell cycle distribution and it impairs phosphorylation of target proteins such as H2AX, CHK2 and KAP1 (Jacquemin_2012, Fievet_2019). Three ClinVar submitters (evaluation after 2014) cite the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 2913 of the ATM protein (p.Asp2913Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with ataxia-telangiectasia and/or prostate cancer (PMID: 21665257, 22071889, 33436325). ClinVar contains an entry for this variant (Variation ID: 230841). 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 expected to disrupt ATM protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects ATM function (PMID: 22071889, 31050087). For these reasons, this variant has been classified as Pathogenic. -

Significance: Likely pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The p.D2913Y variant (also known as c.8737G>T), located in coding exon 59 of the ATM gene, results from a G to T substitution at nucleotide position 8737. The aspartic acid at codon 2913 is replaced by tyrosine, an amino acid with highly dissimilar properties. This alteration has been reported in multiple individuals with a clinical diagnosis of ataxia-telangiectasia in both homozygous and compound heterozygous states (Micol R et al. J. Allergy Clin. Immunol. 2011 Aug;128(2):382-9). Cell lines from an individual with ataxia telangiectasia who was heterozygous for this alteration along with a second alteration in ATM, exhibited decreased response to ionizing radiation, decreased ATM protein expression, and abnormal cellular localization (Jacquemin V et al. Eur. J. Hum. Genet. 2012 Mar;20(3):305-12). Additionally, this alteration has been reported in at least one breast cancer patient in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J Med Genet, 2017 11;54:732-741). This variant was also reported in 1/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 08;4:570-579). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. -

Significance: Likely pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces aspartic acid with tyrosine at codon 2913 of the ATM protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on protein function. Functional studies have shown that this variant results in reduced protein expression, abnormal sub-cellular localization, and disrupted phosphorylation activity (PMID: 22071889, 31050087). This variant has been reported in individuals affected with ataxia-telangiectasia in homozygosity and compound heterozygosity with a known pathogenic co-variant (PMID: 21665257, 31050087). In addition, this variant has been reported in individuals affected with breast cancer (PMID: 28779002, 30128536, 33471991). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Based on available evidence, this variant is classified as Likely Pathogenic. -
