RCV001222651 | SCV001394762 | likely pathogenic | Ataxia-telangiectasia syndrome | 2020-12-24 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). This variant has not been reported in the literature in individuals with ATM-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects a donor splice site in intron 53 of the ATM gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. |
| Ambry Genetics | RCV002418766 | SCV002676550 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2023-08-03 | criteria provided, single submitter | clinical testing | The c.7927+1G>A intronic variant results from a G to A substitution one nucleotide after coding exon 52 of the ATM gene. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic. |
