Ambry Genetics RCV001025161 SCV001187297 likely pathogenic Hereditary cancer-predisposing syndrome 2018-05-09 criteria provided, single submitter clinical testing The c.6348-1G>C intronic variant results from a G to C substitution one nucleotide upstream from coding exon 43 of the ATM gene. This nucleotide position is well conserved in available vertebrate species. Using the BDGP and ESEfinder splice site prediction tools, this alteration is predicted to abolish the native splice acceptor site; however, direct evidence is unavailable. 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.
Invitae RCV001873390 SCV002289078 likely pathogenic Ataxia-telangiectasia syndrome 2021-03-28 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 826338). This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 43 of the ATM gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site 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).
