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]

Benign, criteria provided, single submitter	clinical testing	Spanish ATM Cancer Susceptibility Variant Interpretation Working Group	Jun 17, 2020	The c.2362A>C p.(Ser788Arg) missense variant has an allele frequency of 0.00944 (0.94%, 223/23,614 alleles) in the African population of the gnomAD v2.1.1 non-cancer dataset. Therefore, this variant meets a stand-alone criterion to be classified as benign (BA1; http://gnomad.broadinstitute.org). Adapted ACMG/AMP rules applied as defined by the Spanish ATM working group: BA1 (PMID: 33280026). -
Benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 30, 2018	This alteration is classified as 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. -

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

The ATM p.Ser788Arg variant was identified in 3 of 3974 proband chromosomes (frequency: 0.00075) from individuals or families with Lynch Syndrome, breast cancer and a general healthy ancestrally diverse cohort in a study of germline variation in cancer-susceptibility genes (Bodian 2014, Yurgelun 2015, Ianuzzi 2002). The variant was also identified in dbSNP (ID: rs641252) as â€šÃ„ÃºWith other alleleâ€šÃ„Ã¹ and ClinVar (4x as benign by Invitae, EGL Genetics, Color, GeneDx and 6x as likely benign by University of Chicago Genetic services, Institute for Biomarker, Counsyl, True Health Diagnostics) databases. The variant was not identified in GeneInsight-COGR, Cosmic, MutDB or LOVD 3.0, databases. The variant was identified in control databases in 242 of 276996 chromosomes (2 homozygous) at a frequency of 0.00087 increasing the likelihood this could be a low frequency variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 230 of 24034 chromosomes (freq: 0.0095), Other in 2 of 6466 chromosomes (freq: 0.0003), Latino in 8 of 34420 chromosomes (freq: 0.0002), European Non-Finnish in 2 of 126668 chromosomes (freq: 0.000016), while the variant was not observed in the Ashkenazi Jewish, East Asian, European Finnish, or South Asian populations. The p.Ser788Arg residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 1 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

This variant is considered benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. -
