RCV000522033 | SCV000617378 | likely pathogenic | not provided | 2017-04-20 | criteria provided, single submitter | clinical testing | This variant is denoted ATM c.8793T>A at the cDNA level and p.Cys2931Ter (C2931X) at the protein level. The substitution creates a nonsense variant, which changes a Cysteine to a premature stop codon (TGT>TGA), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in an individual with Ataxia-telangiectasia who also carried a canonical splice variant in ATM; however, phase was not determined (Sandoval 1999). Based on currently available evidence, we consider ATM c.8793T>A to be a likely pathogenic variant. |

RCV000539551 | SCV000622854 | pathogenic | Ataxia-telangiectasia syndrome | 2023-06-05 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 449347). This premature translational stop signal has been observed in individual(s) with ataxia telangiectasia and/or breast cancer (PMID: 9887333, 26556299). This sequence change creates a premature translational stop signal (p.Cys2931*) 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). |
Ambry Genetics | RCV001018342 | SCV001179568 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-09-13 | criteria provided, single submitter | clinical testing | The p.C2931* pathogenic mutation (also known as c.8793T>A), located in coding exon 60 of the ATM gene, results from a T to A substitution at nucleotide position 8793. This changes the amino acid from a cysteine to a stop codon within coding exon 60. This alteration was reported in an individual with ataxia telangiectasia in conjunction with a canonical splice site alteration; however, the phase (whether in cis or trans) is not known (Sandoval N et al. Hum. Mol. Genet., 1999 Jan;8:69-79). 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. |
