The NM_000051.4(ATM):c.2362A>C(p.Ser788Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000481 in 1,613,806 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S788G) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Benign:6
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. - |

Likely benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 28, 2017 | This variant was observed as part of a predisposition screen in an ostensibly healthy population. 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. - |

Malignant tumor of breast Benign:1
Likely benign, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | 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 “With other allele” 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. - |
Familial cancer of breast Benign:1
Benign, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | May 08, 2024 | 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. - |
