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]

Variant summary: ATM c.6114C>G (p.His2038Gln) results in a non-conservative amino acid change located in the PIK-related kinase domain (IPR014009) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251382 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.6114C>G has been reported in the literature in individuals affected with features of Lynch syndrome without evidence of causality (Yurgelun_2015). This report does 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. The following publication has been ascertained in the context of this evaluation (PMID: 25980754). ClinVar contains an entry for this variant (Variation ID: 232340). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.H2038Q variant (also known as c.6114C>G), located in coding exon 41 of the ATM gene, results from a C to G substitution at nucleotide position 6114. The histidine at codon 2038 is replaced by glutamine, an amino acid with highly similar properties. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2038 of the ATM protein (p.His2038Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of Lynch syndrome (PMID: 25980754). ClinVar contains an entry for this variant (Variation ID: 232340). 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. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is denoted ATM c.6114C>G at the cDNA level, p.His2038Gln (H2038Q) at the protein level, and results in the change of a Histidine to a Glutamine (CAC>CAG). This variant was identified in a cohort of 1250 individuals with personal history of Lynch syndrome-associated cancer and/or polyps undergoing genetic testing for Lynch syndrome using a multi-gene panel (Yurgelun 2015). ATM His2038Gln was not observed in large population cohorts (Lek 2016). ATM His2038Gln is located in the FAT domain (Stracker 2013). In-silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether ATM His2038Gln is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -
