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.2836A>G (p.Met946Val) results in a conservative amino acid change located in the PIK-related kinase - FAT domain (IPR003151) of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 251282 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.2836A>G in individuals affected with Ataxia-Telangiectasia and no experimental evidence demonstrating its impact on protein function have been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (VUS, n=5; LB, n=1). Based on the evidence outlined above, the variant was classified as uncertain significance. -

The ATM p.Met946Val variant was identified in 1 of 11178 proband chromosomes (frequency: 0.00009) from German individuals or families with BRCA1/2 negative breast or ovarian cancer (Hauke 2018). The variant was also identified in dbSNP (ID: rs587781992) â€šÃ„ÃºWith Uncertain significance alleleâ€šÃ„Ã¹ and ClinVar (classified as uncertain significance by Ambry Genetics, Invitae, GeneDx and Fulgent Genetics (Fulgent Genetics)) and not identified in LOVD 3.0 database. The variant was identified in control databases in 4 of 277036 chromosomes at a frequency of 0.00001 (Genome Aggregation Database Feb 27, 2017), observed in the following populations: African in 1 of 24038 chromosomes (freq: 0.00004) and European Non-Finnish in 3 of 126682 chromosomes (freq: 0.00002), while not observed in the Other, Latino, Ashkenazi Jewish, East Asian, European Finnish, and South Asian populations. The p.Met946 residue is conserved in in mammals but not in more distantly related organisms however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out pathogenicity. The p.Met946Val variant occurs in the last three bases of the exon. This position has been shown to be part of the splicing consensus sequence and variants involving this position sometimes affect splicing. However, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

The ATM c.2836A>G variant is predicted to result in the amino acid substitution p.Met946Val. This variant has been reported in several individuals with breast cancer (Table S1, Hauke et al. 2018. PubMed ID: 29522266; Supplementary Table 3, de Oliveira et al. 2022. PubMed ID: 35534704). This variant is reported in 0.0040% of alleles in individuals of African descent in gnomAD and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from likely benign to uncertain significance (https://www.ncbi.nlm.nih.gov/clinvar/variation/141763/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
