Invitae RCV000558455 SCV000629863 likely pathogenic Li-Fraumeni syndrome 2017-04-28 criteria provided, single submitter clinical testing This sequence change replaces glycine with valine at codon 245 of the TP53 protein (p.Gly245Val). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and valine. This variant is present in population databases (rs121912656, ExAC 0.01%). This variant has been reported in the literature in individuals with lung cancer, follicular lymphoma, and Li-Fraumeni associated cancers (PMID: 11180592, 11920788, 18628487, 17606709). ClinVar contains an entry for this variant (Variation ID: 376603). Experimental studies have shown that this missense change disrupts the ability of TP53 to bind to DNA and significantly decreases its transcriptional transactivation activity (PMID: 12826609, 17606709). Different missense substitutions at this codon (p.Gly245Asp and p.Gly245Ser ) have been determined to be pathogenic (PMID: 1565143, 24122735, 17311302, 12826609,20128691, 21343334, 25119136, 2259385), further suggesting that the glycine residue is critical for TP53 protein function and that other missense substitutions at this position may also be pathogenic. In summary, this variant is a rare missense change that has been observed in affected individuals and shown to disrupt TP53 protein function. This evidence indicates that the variant is pathogenic, but additional data is needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
