Description

This sequence change creates a premature translational stop signal (p.Met66Asnfs*83) in the TP53 gene. It is expected to result in an absent or disrupted protein product. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in TP53 are known to be pathogenic (PMID: 20522432). This variant has not been reported in the germline of individuals with TP53-related disease. This variant is not present in population databases (ExAC no frequency).
