Description

This sequence change creates a premature translational stop signal (p.Ser660*) in the MRE11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MRE11 are known to be pathogenic (PMID: 23080121, 23912341). This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with MRE11-related conditions. For these reasons, this variant has been classified as Pathogenic.
