RCV001293594 | SCV004672367 | pathogenic | Li-Fraumeni syndrome | 2020-03-12 | criteria provided, single submitter | clinical testing | 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 literature in individuals with TP53-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Phe109Asnfs*38) in the TP53 gene. It is expected to result in an absent or disrupted protein product. |

RCV001293594 | SCV001482210 | likely pathogenic | Li-Fraumeni syndrome | 2021-02-02 | criteria provided, single submitter | clinical testing | Variant summary: TP53 c.324_331delinsAAA (p.Phe109AsnfsX38) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant was absent in 251288 control chromosomes. To our knowledge, no occurrence of c.324_331delinsAAA in individuals affected with Li-Fraumeni Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
