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]

This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 44 of the ATM protein (p.Asp44Gly). This variant is present in population databases (rs150143957, gnomAD 0.05%). This missense change has been observed in individual(s) with breast cancer (PMID: 25186627, 31871109, 35039564, 35534704, 35980532, 36315513). ClinVar contains an entry for this variant (Variation ID: 186471). 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%. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (internal data). 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. -

This missense variant replaces aspartic acid with glycine at codon 44 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 affected with breast cancer (PMID: 31871109, 32959997, 33471991, 35039564, 36315513) and prostate cancer (PMID: 36898365). This variant has been identified in 11/282598 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. -

The p.D44G variant (also known as c.131A>G), located in coding exon 2 of the ATM gene, results from an A to G substitution at nucleotide position 131. The aspartic acid at codon 44 is replaced by glycine, an amino acid with similar properties. In a study of 196 women with breast cancer and 185 unaffected controls from Cameroon and Uganda, this variant was observed in eight women (Adedokun B et al. Cancer Epidemiol Biomarkers Prev, 2020 02;29:359-367). This alteration has been identified in multiple individuals diagnosed with breast cancer (Haiman CA et al. PLoS Genet, 2013 Mar;9:e1003419; Tung N et al. Cancer, 2015 Jan;121:25-33; Uyisenga JP et al. Mol Genet Genomic Med, 2020 11;8:e1500; Eygelaar D et al. Sci Rep, 2022 Jan;12:802; McDonald JT et al. PLoS One, 2022 Oct;17:e0273835). This alteration has also been identified in multiple individuals diagnosed with prostate cancer (Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43; Gheybi K et al. J Natl Compr Canc Netw, 2023 Mar;21:289-296.e3). This amino acid position is highly 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. -

Variant summary: ATM c.131A>G (p.Asp44Gly) results in a non-conservative amino acid change located in the Telomere-length maintenance and DNA damage repair domain (IPR021668) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00019 in 143258 control chromosomes, predominantly at a frequency of 0.0006 within the African or African-American subpopulation in the gnomAD database (v3 genomes dataset). This frequency is somewhat lower than the maximum expected for a pathogenic variant in ATM causing Breast Cancer (0.0006 vs 0.001), allowing no conclusion about variant significance. In addition, this variant has been reported in 2/2559 African American women and 1/7325 European American women, who were older than age 70 and cancer free (in the FLOSSIES database). The variant, c.131A>G, has also been reported in the literature in African- or African-American individuals affected with Breast Cancer (Haiman_2013, Tung_2015, Adedokun_2020). These reports however do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and all of them classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
