Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6

The NM_000051.4(ATM):c.4365T>A(p.Ser1455Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000353 in 1,613,784 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S1455N) has been classified as Uncertain significance.

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]

Review Status:criteria provided, single submitter

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. -

This missense variant replaces serine with arginine at codon 1455 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. Functional studies reported loss of kinase activity in irradiated cells and a failure to complement cell survival phenotypes in ATM-defective cells (PMID: 12969974, 29059438). In a breast cancer case-control study conducted in Japan, this variant was detected in 31/7051 female breast cancer cases, 80/11241 female controls, 1/53 male breast cancer cases, and 65/12490 male controls (PMID: 30287823). In a colorectal cancer case-control study conducted in Japan, this variant was detected in 71/12503 colorectal cancer cases and 145/23705 controls (PMID: 33309985). This variant has also been reported in individuals affected with breast cancer, prostate cancer, Hodgkin lymphoma, and neuroblastoma (PMID: 12969974, 28779002, 29059438, 35534218). This variant has been identified in 1/251188 chromosomes in the general population by the Genome Aggregation Database (gnomAD) and in control individuals (PMID: 12969974, 29059438). 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 benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

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.4365T>A (p.Ser1455Arg) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00049 in 298850 control chromosomes (gnomAD and publications), predominantly at a frequency of 0.0031 within the Japanese subpopulation (Takagi_2004, Momozawa_2018). The observed variant frequency within Japanese control individuals is approximately 3-fold of the estimated maximal expected allele frequency for a pathogenic variant in ATM causing Breast Cancer phenotype (0.001), strongly suggesting that the variant is a benign polymorphism. c.4365T>A has been reported in the literature in individuals affected with cancer including pediatric Hodgkin disease, neuroblastoma, breast, prostate and colorectal cancer (Takagi_2004, Decker_2017, Takagi_2017, Momozawa_2018, Fujita_2022, So_2022). However, case-control studies in Japanese individuals have also identified the variant in high frequency in controls and concluded it to be benign (Momozawa_2018, Fujita_2022). Co-occurrences with pathogenic variants have been reported via internal testing (MSH2 c.1204C>T, p.Gln402X; BRCA1 c.5467+1G>A), providing supporting evidence for a benign role. Experimental evidence demonstrated the variant to have an impact on protein function, however, do not allow convincing conclusions about the variant effect (Takagi_2017). Two ClinVar submitters (evaluation after 2014) cite the variant as likely benign and four ClinVar submitters (evaluation after 2014) cite it as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -
