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]

Submissions by phenotype
Ataxia-telangiectasia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 12, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 453648). This premature translational stop signal has been observed in individual(s) with ataxia telangiectasia and/or breast cancer (PMID: 19535770, 32068069). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu2304Serfs*6) 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). - |

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 23, 2023 | The c.6910delG pathogenic mutation, located in coding exon 46 of the ATM gene, results from a deletion of one nucleotide at nucleotide position 6910, causing a translational frameshift with a predicted alternate stop codon (p.E2304Sfs*6). This alteration was observed in 1 of 1338 Chinese high-risk breast cancer patients and 1 of 2160 Chinese colorectal cancer patients (Kwong A et al. J Mol Diagn, 2020 Apr;22:544-554; Liao H et al. Am J Cancer Res, 2021 Nov;11:5571-558). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. - |
