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]

Available data are insufficient to determine the clinical significance of the variant at this time. The frequency of this variant in the general population is uninformative in assessment of its pathogenicity (http://gnomad.broadinstitute.org). Assessment of experimental evidence regarding the effect of this variant on protein function suggests it has no effect relevant to disease. (PMID: 19431188, 11805335) -

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

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

The c.6820G>A variant has been reported in individuals with breast cancer (Broeks 2008, Li 2016 ) but did not segregate with disease in two families with breast and ovarian cancer (Thorstenson 2003). The c.6820G>A variant has also been reported in the literature to co-occur with the ATM c.4724G>A variant in individuals with breast cancer, chronic lymphocytic leukemia (CLL) and multiple myeloma (Austen 2008, Tavtigian 2008, and Navrkalova 2012). The individual with CLL also had a somatic ATM Gln984Glu and a somatic 11q chromosomal deletion. The c.6820 variant has a combined allele frequency of 0.00009 in the Broad Institute gnomAD Browser (https://gnomad.broadinstitute.org/). In silico analyses indicate that this variant is in an evolutionarily conserved residue. Thus, it is unknown whether this variant increases cancer risk. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Variant summary: ATM c.6820G>A (p.Ala2274Thr) results in a non-conservative amino acid change located in the FAT domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00011 in 271674 control chromosomes, predominantly at a frequency of 0.00021 within the Non-Finnish European subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in ATM causing Breast Cancer (0.00011 vs 0.001), allowing no conclusion about variant significance. c.6820G>A has been reported in the literature in individuals with breast cancer (at least 5 patients), multiple myeloma (at least 1 patient) and at least 2 patients with chronic lymphocytic leukemia (example, Stankovic_1999, Dork_2001, Thorstenson_2003, Austen_2008, Broeks_2008, Tavtigian_2009, Skowronska_2011, Navrkalova_2012, Li_2016). In two reported HBOC families, this variant did not cosegregate with disease, suggesting a notion that it does not cause HBOC (Thorstenson_2003). However, the variants role as risk allele cannot be ruled out as the variant was found in a meta-analysis to be overrepresented in a patient population compared to a control population (Tavtigian_2009). These data do not allow any conclusion about variant significance. Multiple publications report experimental evidence evaluating an impact on protein function. These results showed no damaging effect of this variant as demonstrated by protein expression, kinase activity, and radiation-induced chromosome aberrations assays (Scott 2002, Barone 2009). The following publications have been ascertained in the context of this evaluation (PMID: 18573109, 19431188, 17393301, 11606401, 26534844, 23585524, 27978560, 11805335, 21933854, 10023947, 19781682, 12810666, 28652578, 27449771). Ten submitters have cited clinical-significance assessments for this variant to ClinVar after 2014 (likely benign, n=3, VUS, n=6, Pathogenic, n=1). Some submitters cite overlapping evidence utilized in the context of this evaluation. Based on the lack of actionable clinical and functional evidence outlined above, the variant was classified as likely benign. -
