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
Familial cancer of breast Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Baylor Genetics | Oct 17, 2023 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Feb 06, 2024 | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. - |
Ataxia-telangiectasia syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 10, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 407645). This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia (PMID: 10817650). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Trp2960*) 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). - |
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Oct 20, 2021 | Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 27324988, 10817650) - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 30, 2021 | The p.W2960* pathogenic mutation (also known as c.8880G>A), located in coding exon 61 of the ATM gene, results from a G to A substitution at nucleotide position 8880. This changes the amino acid from a tryptophan to a stop codon within coding exon 61. 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. - |
