GeneDx RCV000657363 SCV000779095 likely pathogenic not provided 2017-07-28 criteria provided, single submitter clinical testing This deletion of two nucleotides in ATM is denoted c.5209_5210delTT at the cDNA level and p.Leu1737GlufsX11 (L1737EfsX11) at the protein level. The normal sequence, with the bases that are deleted in brackets, is CTGT[delTT]GAAA. The deletion causes a frameshift which changes a Leucine to a Glutamic Acid at codon 1737, and creates a premature stop codon at position 11 of the new reading frame. Although this variant has not, to our knowledge, been reported in the literature, it is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. Based on the currently available information, we consider this deletion to be a likely pathogenic variant.
Invitae RCV000627938 SCV000748823 pathogenic Ataxia-telangiectasia syndrome 2018-02-07 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu1737Glufs*11) in the ATM gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with ATM-related disease. Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic.
