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]

The ATM p.Ser707Pro variant was identified in 542 of 44368 proband chromosomes (frequency: 0.0122) from individuals or families with breast and thyroid cancer and was present in 6 of 1000 control chromosomes (frequency: 0.006) from healthy individuals (Dork 2001, Barbazetto 2008, Dombernowsky 2008, Fletcher 2010, Petereit 2013, Spurdle 2002). The variant was also identified in dbSNP (ID: rs4986761) as other, ClinVar (classified as benign by GeneDx, Ambry genetics, Emory genetics, Color Genomics, Invitae), Cosmic (classified as neutral), MutDB (classified as polymorphism), and LOVD 3.0 databases. The variant was not identified in GeneInsight-COGR and ATM-LOVD databases. The variant was identified in control databases in 2208 of 276136 chromosomes at a frequency of 0.007996 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Consortium Feb 27, 2017). The variant was identified in the following populations at a frequency greater than 1%: European (Non-Finnish) (6 homozygous) in 1508 of 126110 chromosomes (freq: 0.012), Other in 70 of 6438 chromosomes (freq: 0.011). In one study, the p.Ser707Pro variant appeared to be associated with high-risk breast carcinoma, characterized by a positive axillary nodal status and an increased risk of contralateral breast cancer (Dork, 2001). The p.Ser707Pro variant is likely to interfere with secondary and tertiary protein structure, as the exchange of proline for serine introduces a much bulkier side chain and removes a hydroxyl group that possibly participates in hydrogen bonding (Dork, 2001). However, several large population studies have shown that the variant was not associated with an increased breast cancer risk compared with the general population, or overall cancer risk (Barbazetto 2008, Choi 2016, Fletcher 2010, Spurdle 2002). In addition, in their study Thorstenson (2003) found the variant did not segregate with disease. The p.Ser707Pro residue is not conserved in mammals and mammals and the variant amino acid Proline (Pro) is present in several lower organisms, increasing the likelihood that this variant does not have clinical significance. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. The variant is located with the Armadillo-type fold functional domain(s), the clinical significance of which cannot be determined. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

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). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

This alteration is classified as 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. -

This variant is considered benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
