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 histidine, which is basic and polar, at codon 2913 of the ATM protein (p.Asp2913His). This variant is present in population databases (rs756899044, gnomAD 0.0009%). This missense change has been observed in individual(s) with prostate cancer (PMID: 33436325). ClinVar contains an entry for this variant (Variation ID: 231464). 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. This variant disrupts the p.Asp2913 amino acid residue in ATM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 21665257, 22071889). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.D2913H variant (also known as c.8737G>C), located in coding exon 59 of the ATM gene, results from a G to C substitution at nucleotide position 8737. The aspartic acid at codon 2913 is replaced by histidine, an amino acid with similar properties. A different alteration at this position, p.D2913Y, has been reported in multiple individuals with a clinical diagnosis of ataxia-telangiectasia in both homozygous and compound heterozygous states (Micol R et al. J. Allergy Clin. Immunol. 2011 Aug;128:382-9). Cell lines from an individual with ataxia telangiectasia who was heterozygous for p.D2913Y along with a second alteration in ATM, exhibited decreased response to ionizing radiation, decreased ATM protein expression, and abnormal cellular localization (Jacquemin V et al. Eur. J. Hum. Genet. 2012 Mar;20:305-12). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
