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]

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Feb 01, 2020	The ATM c.712A>G; p.Ile238Val variant (rs754275014) is reported in the literature in an individual with colorectal cancer (Pearlman 2017), and individuals with breast cancer but was also reported in healthy controls (Momozawa 2018). This variant is reported in the ClinVar database (Variation ID: 186210). It is found in the general population with an overall allele frequency of 0.002% (4/251040 alleles) in the Genome Aggregation Database. The isoleucine at codon 238 is moderately conserved, but computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. Due to limited information, the clinical significance of this variant is uncertain at this time. REFERENCES Momozawa Y et al.

Hereditary cancer-predisposing syndrome

Uncertain:2Benign:1

Uncertain significance, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Dec 11, 2023	This missense variant replaces isoleucine with valine at codon 238 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast cancer, ovarian cancer, or colorectal cancer (PMID: 26689913, 27978560, 30287823, 33471991). This variant has been identified in 4/251040 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. -
Uncertain significance, criteria provided, single submitter	curation	Sema4, Sema4	Sep 01, 2021	- -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 19, 2019	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Ataxia-telangiectasia syndrome

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 31, 2022	This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 238 of the ATM protein (p.Ile238Val). This variant is present in population databases (rs754275014, gnomAD 0.003%). This missense change has been observed in individual(s) with colorectal cancer, breast cancer, and ovarian cancer (PMID: 26689913, 27978560, 30287823). ClinVar contains an entry for this variant (Variation ID: 186210). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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. -
