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]

Submissions by phenotype

Ataxia-telangiectasia syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 18, 2024	This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 1182 of the ATM protein (p.Glu1182Gln). This variant is present in population databases (rs377349886, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 407566). 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. -

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 07, 2023	The p.E1182Q variant (also known as c.3544G>C), located in coding exon 23 of the ATM gene, results from a G to C substitution at nucleotide position 3544. The glutamic acid at codon 1182 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Variant summary: ATM c.3544G>C (p.Glu1182Gln) 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 1.6e-05 in 251340 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.3544G>C in individuals affected with Breast Cancer and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 407566). Based on the evidence outlined above, the variant was classified as uncertain significance. -

The ATM c.3544G>C variant is predicted to result in the amino acid substitution p.Glu1182Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.028% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-108151863-G-C); and, it is interpreted as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/407566/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
