Description

This sequence change creates a premature translational stop signal (p.Ser644*) 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 been reported in individuals affected with gastric cancer (PMID: 26098866) and pancreatic cancer (PMID: 23561644, 25479140). Additionally this variant has been reported in combination with another ATM variant in an individual affected with ataxia telangiectasia (PMID: 10817650). ClinVar contains an entry for this variant (Variation ID: 233607). Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic.
