Invitae RCV000708054 SCV000837164 pathogenic Ataxia-telangiectasia syndrome 2019-11-25 criteria provided, single submitter clinical testing This variant is a gross deletion of the genomic region encompassing exons 17-63 of the ATM gene. The 5' boundary is likely confined to intron 16. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. Deletion of exons 17-63 has not been reported in the literature in individuals with ATM-related disease. This gross deletion eliminates the last 2,234 amino acid residues of the ATM protein, including the FAT, PI3/4 kinase, and FATC or PIK-related kinase domains, which are crucial for the proper function of the ATM protein (PMID: 23532176, 25460276, 19781682). In addition, several downstream gross deletions encompassing exons 38-63, exons 46-63, exons 57-63 and exons 62-63 of ATM have been reported in individuals with ataxia-telangiectasia, and determined to be pathogenic (PMID: 25614872, 23807571, 9443866, 25614872). This suggests that deletion of this region of the ATM protein is causative of disease. For these reasons, this variant has been classified as Pathogenic.
