Variant summary: ATM c.737A>G (p.Asn246Ser) results in a 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 4.1e-06 in 245766 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.737A>G in individuals affected with breast cancer and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. (less)

The ATM c.737A>G (p.N246S) variant has been reported in several individuals with breast cancer (PMID: 30613976, 33785725, 33471991, 30287823), as well as in a healthy people (PMID: 32980694). It was observed in 1/30610 chromosomes in the South Asian population in the large and broad cohorts of the Genome Aggregation Database (http://gnomad.broadinstitute.org, PMID: 32461654), and has been reported in ClinVar (Variation ID 524424). Functional studies have not been performed, and in silico predictions of the variant's effect on protein function are inconclusive. The evidence is insufficient to meet ACMG/AMP criteria for classifying the variant as benign or pathogenic. Thus, the clinical significance of this variant is currently uncertain. (less)

This missense variant replaces asparagine with serine at codon 246 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. In a large international case-control study, this variant was reported in 3/60466 breast cancer cases and absent in 53461 controls (PMID: 33471991). This variant has been reported in an individual affected with early-onset breast cancer (PMID: 33785725). This variant has been identified in 1/251014 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. (less)

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 246 of the ATM protein (p.Asn246Ser). This variant is present in population databases (rs781023264, gnomAD 0.003%). This missense change has been observed in individual(s) with early-onset breast cancer and/or male breast cancer (PMID: 30613976, 33785725). ClinVar contains an entry for this variant (Variation ID: 524424). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. (less)

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.

This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number.
