Invitae RCV000698744 SCV000827427 likely pathogenic Li-Fraumeni syndrome 2018-05-17 criteria provided, single submitter clinical testing This sequence change replaces arginine with serine at codon 273 of the TP53 protein (p.Arg273Ser). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and serine. This variant is present in population databases (rs121913343, ExAC 0.006%). This variant has been observed in an individual affected with osteosarcoma and in two families with Li-Fraumeni syndrome (PMID: 8164043, 18685109, 25584008). ClinVar contains an entry for this variant (Variation ID: 376656). Experimental studies have shown that this missense change significantly impairs the transcriptional transactivation activity of the TP53 protein and was shown to interfere with wild-type TP53 protein function in a dominant-negative manner (PMID: 12826609, 12917626, 15017592, 21343334). The p.Arg273 amino acid residue in TP53 has been determined to be clinically significant (PMID: 2826609, 8479749, 21535297, 21552135, 17606709, 17540308, 9242456, 21484931, 1565144). This suggests that variants that disrupt this residue are likely to be causative of disease. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
