Labcorp Genetics (formerly Invitae), Labcorp RCV000239985 SCV000299136 likely pathogenic Ataxia-telangiectasia syndrome 2016-06-17 criteria provided, single submitter clinical testing This variant is a gross duplication of the genomic region encompassing exons 17-61 of the ATM gene. While the exact position of the duplicated exons cannot be determined from this data, the duplicated copy of this region is likely in tandem and in-frame, therefore preserving the integrity of the reading frame. This variant has been observed in trans with a pathogenic ATM variant in an affected individual (Invitae database). If in tandem, this variant leads to duplication of >2000 amino acid residues in the ATM protein, which likely interferes with proper protein folding and function. In summary, this is a gross duplication with uncertain impact on protein function. However, since it has been observed in an affected individual in a compound heterozygous state, it has been classified as a Likely Pathogenic.
