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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 231 of the ATM protein (p.His231Arg). This variant is present in population databases (rs587782229, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer and/or clinical features of ataxia-telangiectasia (PMID: 12810666, 17124347, 19781682, 35534704). ClinVar contains an entry for this variant (Variation ID: 142096). 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. -

Significance:Uncertain significance

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. -

Collection Method:clinical testing

The p.H231R variant (also known as c.692A>G), located in coding exon 6 of the ATM gene, results from an A to G substitution at nucleotide position 692. The histidine at codon 231 is replaced by arginine, an amino acid with highly similar properties. In one study, this alteration was detected in 1/4112 breast cancer patients and 0/2399 healthy control individuals (Tavtigian S et al. Am. J. Hum. Genet. 2009 Oct;85(4):427-46). This alteration was also reported in a cohort of 270 Austrian HBOC families previously screened for BRCA1 and BRCA2 mutations (Thorstenson YR et al. Cancer Res, 2003 Jun;63:3325-33). This variant was also detected in an Italian individual with classic ataxia telangiectasia; however, a second alteration was not identified (Magliozzi M et al. Dis. Markers. 2006;22(4):257-64). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This missense variant replaces histidine with arginine at codon 231 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals or families affected with breast cancer (PMID: 12810666, 19781682, 33471991). The variant has also been observed heterozygous in an individual affected with ataxia-telangiectasia, but without a known second mutation (PMID: 17124347). This variant has been identified in 4/251096 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. -
