GeneDx RCV000483137 SCV000568325 pathogenic not provided 2016-11-09 criteria provided, single submitter clinical testing This variant is denoted ATM c.4852C>T at the cDNA level and p.Arg1618Ter (R1618X) at the protein level. The substitution creates a nonsense variant, which changes an Arginine to a premature stop codon (CGA>TGA), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in the heterozygous state in at least one case of breast cancer and in the compound heterozygous state in at least one case of ataxia-telangiectasia (Paglia 2010, Hacia 1998), and is considered pathogenic.
Invitae RCV000525721 SCV000622535 pathogenic Ataxia-telangiectasia syndrome 2018-10-01 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg1618*) in the ATM gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs762083530, ExAC 0.006%). This variant has been observed in the homozygous and compound heterozygous state in individuals affected with ataxia telangiectasia (PMID: 9872980, 15843990). This variant has also been reported in the heterozygous state in an individual affected with breast cancer (PMID: 19404735). ClinVar contains an entry for this variant (Variation ID: 187207). Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic.
