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]
C11orf65 (HGNC:28519): (chromosome 11 open reading frame 65) Predicted to be involved in negative regulation of mitochondrial fission and negative regulation of protein targeting to mitochondrion. Predicted to be located in cytosol and mitochondrial outer membrane. [provided by Alliance of Genome Resources, Apr 2022]

Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | May 01, 2020 | Variant summary: ATM c.7010_7011delGT (p.Cys2337SerfsX35) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251078 control chromosomes (gnomAD). c.7010_7011delGT has been reported in the literature in multiple individuals affected with Ataxia-Telangiectasia (Telatar_1996, Telatar_1998, Li_2000, Buzin_2003, Podralska_2014). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 27, 2024 | This sequence change creates a premature translational stop signal (p.Cys2337Serfs*35) in the ATM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia (PMID: 8659541, 9443866, 16266405, 25614872). This variant is also known as 7009delTG. ClinVar contains an entry for this variant (Variation ID: 220198). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 14, 2022 | The c.7010_7011delGT pathogenic mutation, located in coding exon 47 of the ATM gene, results from a deletion of two nucleotides at nucleotide positions 7010 to 7011, causing a translational frameshift with a predicted alternate stop codon (p.C2337Sfs*35). This mutation has been well documented in the literature in a compound heterozygous state in multiple individuals with Ataxia Telangiectasia (A-T) (Buzin CH et al. Hum. Mutat. 2003 Feb; 21(2):123-31; Li A et al. Am. J. Med. Genet. 2000 May; 92(3):170-7; Mitui M et al. Ann. Hum. Genet. 2005 Nov; 69(Pt 6):657-64; Podralska MJ et al. Mol Genet Genomic Med. 2014 Nov; 2(6):504-11). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Jan 25, 2021 | This variant deletes 2 nucleotides in exon 48 of the ATM gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with ataxia telangiectasia (PMID: 8659541, 9443866, 16266405, 25614872). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of ATM function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. - |
