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 variant is denoted ATM c.6374A>G at the cDNA level, p.His2125Arg (H2125R) at the protein level, and results in the change of a Histidine to an Arginine (CAT>CGT). This variant was observed at the somatic level in prostate cancer and mantle cell lymphoma tumor tissue samples (Kridel 2012, Grasso 2012, Meissner 2013). Fang et al. (2003) reported that ATM His2125Arg was likely present in the germline of a mantle cell lymphoma patient based on the presence of wild-type alleles in the tumor. ATM His2125Arg was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Histidine and Arginine share similar properties, this is considered a conservative amino acid substitution. ATM His2125Arg occurs at a position that is conserved across species and is located in the FAT domain (Tavtigian 2009). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available information, it is unclear whether ATM His2125Arg is pathogenic or benign. We consider it to be a variant of uncertain significance. -

The p.H2125R variant (also known as c.6374A>G), located in coding exon 43 of the ATM gene, results from an A to G substitution at nucleotide position 6374. The histidine at codon 2125 is replaced by arginine, an amino acid with highly similar properties. This variant has been detected in conjunction with an ATM likely pathogenic variant in an individual with clinical features of ataxia-telangiectasia (Perez Maturo J et al. J Hum Genet, 2020 Oct;65:895-902, Salinas V et al. Am J Med Genet C Semin Med Genet, 2020 Dec;184:876-884). 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. -
