Invitae | RCV001089794 | SCV001245288 | pathogenic | Ataxia-telangiectasia syndrome | 2019-04-26 | criteria provided, single submitter | clinical testing | This sequence change inserts a large fragment of DNA, likely a transposable element, in exon 30 of the ATM gene (c.4493_4494insSVA), causing a frameshift at codon 1498 (p.Leu1498fs). The exact size and sequence of the insertion cannot be determined by the current assay. However, the insertion is expected to result in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with ATM-related conditions. Retrotransposon insertions including LINE1 (L1), Alu, and SVA (SINE-VNTR-Alu) have been reported to be disease-causing through disruption of either a coding region or splice site (PMID: 19763152, 20307669, 22406018) and loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic. |
