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]

Collection Method: clinical testing

The p.S1232P variant (also known as c.3694T>C), located in coding exon 24 of the ATM gene, results from a T to C substitution at nucleotide position 3694. The serine at codon 1232 is replaced by proline, an amino acid with similar properties. This alteration was not observed in 7,051 unselected female breast cancer patients, though was observed with an allele frequency of 0.00018 in 11,241 female controls of Japanese ancestry. In addition, it was not observed in unselected male breast cancer patients or male controls of Japanese ancestry (Momozawa Y et al. Nat Commun, 2018 10;9:4083). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces serine with proline at codon 1232 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 4/248336 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. -

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 1232 of the ATM protein (p.Ser1232Pro). This variant is present in population databases (rs183532834, gnomAD 0.009%). This missense change has been observed in individual(s) with unspecified cancer (PMID: 28873162). ClinVar contains an entry for this variant (Variation ID: 567819). 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 not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -

Variant summary: ATM c.3694T>C (p.Ser1232Pro) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 248336 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.3694T>C has been reported in the literature in at least one individual affected with advanced cancer without clinical information or evidence of cosegregation (Mandelker_2017). The variant has been reported as a VUS in the Japanese population based on its occurrence in 2/11241 controls but not in 7051 breast cancer cases in women (e.g. Momozawa_2018). These reports do not provide unequivocal conclusions about association of the variant with Ataxia Telangiectasia or Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven other submitters have provided clinical-significance assessments for this variant to ClinVar after 2014, and all laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
