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]

The ATM c.5882A>G (p.Tyr1961Cys) variant has a classification of uncertain for Ataxia Telangiectasia (AT) as there is limited evidence regarding the association with this variant and AT in homozgyous or compound heterozygous individuals. However, this variant has been found to be associated with more severe personal and family histories of cancer and is therefore classified as likely pathogenic for hereditary cancer risk. Please note: this variant was assessed in the context of healthy population screening. -

a variant of uncertain significance in the ATM gene (p.Tyr1961Cys). This sequence change replaces tyrosine with cysteine at codon 1961 of the ATM protein (p.Tyr1961Cys). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and cysteine. This variant is present in population databases (rs56399311, gnomAD 0.004%). This variant has been observed in individuals affected with prostate cancer, pancreatic cancer, chronic lymphocytic leukemia, and T-cell lymphoblastic leukemia (PMID: 25479140, 9622061, 21933854, Invitae). However, in one of these individuals’ pathogenic alleles were also identified in ATM, which suggests that this c.5882A>G variant was not the primary cause of disease. ClinVar contains 9 entries for this variant (Variation ID: 127413), all of which interpreted this variant as of uncertain significance. This variant has been predicted as damaging by Polyphen and SIFT. 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 ATM c.5882A>G (p.Tyr1961Cys) variant is considered likely pathogenic for hereditary cancer risk. This variant is strongly associated with more severe personal and family histories of cancer, typical for individuals with pathogenic ATM variants [PMID: 25085752]. However, at this time, it is unclear whether homozygous or compound heterozygous inheritance of this variant causes the recessive condition ataxia telangiectasia (AT). -

Collection Method:clinical testing

The p.Y1961C variant (also known as c.5882A>G), located in coding exon 38 of the ATM gene, results from an A to G substitution at nucleotide position 5882. The tyrosine at codon 1961 is replaced by cysteine, an amino acid with highly dissimilar properties. This alteration has been reported in a patient with CLL and was shown to confer reduced, but not absent ATM kinase activity in in vitro studies (Barone G et al. Hum. Mutat. 2009 Aug;30:1222-30). This alteration has also been reported in breast and pancreatic cancer patients (Grant RC et al. Gastroenterology, 2015 Mar;148:556-64; Young EL et al. J. Med. Genet., 2016 06;53:366-76; Decker B et al. J. Med. Genet., 2017 11;54:732-741; Chaffee KG et al. Genet. Med., 2018 01;20:119-127; Tsaousis GN et al. BMC Cancer, 2019 Jun;19:535; Germani A et al. J Clin Med, 2020 Sep;9). 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 variant remains unclear. -

PS3_Supporting c.5882A>G, located in exon 39 of the ATM gene, is predicted to result in the substitution of tyrosine by cysteine at codon 1961, p.(Tyr1961Cys). This variant is found in 9/117911 at a filtered allele frequency of 0.004% in the gnomAD v2.1.1 database (European non-Finnish non-cancer data set). The SpliceAI algorithm predicts no significant impact on splicing and the REVEL meta-predictor score (0.611) for this variant is indeterminate regarding the effect that it may have on protein function. A functional study has shown reduced kinase activity (PMID: 19431188)(PS3_Supporting). In addition, the variant was also identified in ClinVar (12x uncertain significance, 1x likely benign) and in the LOVD (2x uncertain significance, 2x not provided) databases. Based on currently available information, the variant c.5882A>G is classified as an uncertain significance variant according to ClinGen-ATM Guidelines version v1.1. -

This missense variant replaces tyrosine with cysteine at codon 1961 of the ATM protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function. A functional study has shown that the variant results in reduced ATM kinase activity in a cell line-based assay (PMID: 19431188). This variant has been reported in individuals affected with breast or pancreatic cancer (PMID: 25479140, 28726808, 28779002, 38354330). In a large case-control study, this variant was reported in 5/60461 breast cancer cases and 2/53459 controls (PMID: 33471991). This variant has also been identified in 10/251076 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. -

The ATM c.5882A>G; p.Tyr1961Cys variant (rs56399311; ClinVar ID: 127413) is reported in the literature in several individuals affected with breast cancer or leukemia, although its clinical significance was not demonstrated (Barone 2009, Decker 2017, Girard 2019, Royo 2022). This variant is found in the general population with an overall allele frequency of 0.004% (10/251,076 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.611), although functional studies suggest the variant has reduced kinase activity (Barone 2009). Due to limited information, the clinical significance of this variant is uncertain at this time. References: Barone G et al.

Variant summary: ATM c.5882A>G (p.Tyr1961Cys) results in a non-conservative amino acid change in 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 4e-05 in 251076 control chromosomes, predominantly at a frequency of 7.9e-05 within the Non-Finnish European subpopulation in the gnomAD database. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. This variant has been reported in multiple patients with CLL, breast cancer, or pancreatic cancer, without strong evidence supporting pathogenicity of this variant (Luo_1998, Austen_2005, Greenman_2007, Skowronska_2011, Grant_2015, Young_2015, Chaffee_2018, Girard_2019, Tsaousis_2019). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. One publication lists the variant as having reduced ATM Kinase activity but does not provide data supporting this statement (Barone_2009). The following publications have been ascertained in the context of this evaluation (PMID: 16014569, 19431188, 28726808, 30303537, 25479140, 17344846, 9622061, 26837699, 21933854, 28652578, 31159747, 26787654). ClinVar contains an entry for this variant (Variation ID: 127413). Based on the evidence outlined above, the variant was classified as uncertain significance. -
