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]

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

The c.1695A>G variant (also known as p.E565E), located in coding exon 10 of the ATM gene, results from an A to G substitution at nucleotide position 1695. This nucleotide substitution does not change the amino acid at codon 565. In silico splice site analysis predicts that this alteration will result in the creation or strengthening of a novel splice donor site. RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data). Based on the majority of available evidence to date, this variant is likely to be pathogenic. -

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

This variant causes an A to G nucleotide substitution at the 1695 position of the ATM gene. Splice site prediction tools suggest that this variant may impact RNA splicing. This variant has been reported to impact RNA splicing by an external laboratory, however, detailed data are not available for review (ClinVar SCV000547136.8, SCV000660618.4). This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 3/282680 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. -

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

Variant summary: ATM c.1695A>G alters a non-conserved nucleotide resulting in a synonymous change. Several computational tools predict a significant impact on normal splicing: four predict the variant strengthens a cryptic 5' donor site. Internal data on RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein due to an out of frame product, r.1696_1802del (p.Val566*) that is predicted to undergo nonsense mediated decay (NMD) (Internal data). The variant allele was found at a frequency of 8e-06 in 251276 control chromosomes (gnomAD v2.1), including two carriers who were above age 75 year and were also part of the non-cancer datasets (gnomAD v2.1 and v3.1). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1695A>G in individuals affected with Ataxia-Telangiectasia (or other ATM-related phenotypes) have been reported. ClinVar contains an entry for this variant (Variation ID: 407723), and at-least two ClinVar submitters reported abnormal splicing in the set of samples tested (Ambry and our partner laboratory Labcorp Genetics, formerly Invitae internal data). Based on the evidence outlined above, the variant was classified as likely pathogenic Autosomal Recessive Ataxia-Telangiectasia and Autosomal Dominant susceptibility to Breast Cancer. -

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

This sequence change affects codon 565 of the ATM mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ATM protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or altered protein product. This variant is present in population databases (rs780932013, gnomAD 0.002%). 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: 407723). Studies have shown that this variant results in activation of a cryptic splice site, and produces a non-functional protein and/or introduces a premature termination codon (external communication, internal data). For these reasons, this variant has been classified as Pathogenic. -
