GeneDx RCV000657502 SCV000779237 pathogenic not provided 2018-04-09 criteria provided, single submitter clinical testing This deletion of one nucleotide in ATM is denoted c.7880delA at the cDNA level and p.Tyr2627LeufsX4 (Y2627LfsX4) at the protein level. The normal sequence, with the base that is deleted in brackets, is GCTT[delA]TATT. The deletion causes a frameshift which changes a Tyrosine to a Leucine at codon 2627, and creates a premature stop codon at position 4 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. We consider this variant to be pathogenic.
Invitae RCV000409111 SCV000937541 pathogenic Ataxia-telangiectasia syndrome 2018-07-17 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Tyr2627Leufs*4) 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. ClinVar contains an entry for this variant (Variation ID: 370576). Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic.
