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 1790 of the ATM protein (p.Asp1790Gly). This variant is present in population databases (rs746945284, gnomAD 0.02%). This missense change has been observed in individual(s) with breast cancer (PMID: 30287823, 35218119). ClinVar contains an entry for this variant (Variation ID: 631466). 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 tolerated. 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. -

The p.D1790G variant (also known as c.5369A>G), located in coding exon 35 of the ATM gene, results from an A to G substitution at nucleotide position 5369. The aspartic acid at codon 1790 is replaced by glycine, an amino acid with similar properties. his alteration has been reported with a carrier frequency of 0.00057 in 7051 unselected breast cancer patients and 0.00053 in 11241 female controls of Japanese ancestry (Momozawa Y et al. Nat Commun, 2018 10;9:4083). This alteration has also been reported with a carrier frequency of 0.00013 in 7636 unselected prostate cancer patients and 0.00024 in 12366 male controls of Japanese ancestry (Momozawa Y et al. J Natl Cancer Inst, 2020 Apr;112:369-376). This amino acid position is highly 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. -

This missense variant replaces aspartic acid with glycine at codon 1790 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 been reported in individuals affected with breast cancer as well as in unaffected controls (PMID: 30287823, 33471991). This variant has been identified in 4/250996 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. -
