GeneDx RCV000255425 SCV000322118 likely pathogenic not provided 2016-06-06 criteria provided, single submitter clinical testing This variant is denoted TP53 c.578A>G at the cDNA level, p.His193Arg (H193R) at the protein level, and results in the change of a Histidine to an Arginine (CAT>CGT) in exon 6. While TP53 His193Arg has been reported as one of the most commonly observed somatic TP53 variants, it has also been reported as a germline variant in one individual with a history of sarcoma and breast cancer; both cancers diagnosed at young ages (Frebourg 1995, Brachmann 2004). This variant was shown to result reduced DNA binding compared to WT for three reporter genes representing cell cycle arrest, apoptosis and auto-regulation; all three considered to be major p53 dependent pathways (Malcikova 2010). Additionally, Monti et al. (2011) considers TP53 His193Arg to be a severe deficiency allele with mean residual transactivation activity being 1%. This variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. Since Histidine and Arginine share similar properties, this is considered a conservative amino acid substitution. TP53 His193Arg occurs at a position that is conserved across species and is located within a region that interacts with HIPK1, AXIN1 and is required for interaction with ZNF385A and FBXO42 (UniProt). In silico analyses predict that this mutation is probably damaging to protein structure and function. Based on the currently available information, we consider TP53 His193Arg to be a variant, expected pathogenic.

Invitae RCV000460847 SCV000545345 likely pathogenic Li-Fraumeni syndrome 2018-12-04 criteria provided, single submitter clinical testing This sequence change replaces histidine with arginine at codon 193 of the TP53 protein (p.His193Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in individuals with a personal and/or family history of Li-Fraumeni syndrome associated tumors (PMID: 7887414, 22265402, 25945745, 28724667, Invitae). ClinVar contains an entry for this variant (Variation ID: 184979). Numerous experimental studies in model organisms have shown that this missense change disrupts the transcriptional transactivation activity of the TP53 protein, and may act in a dominant-negative manner (PMID: 9627118, 12826609, 16861262, 20128691, 21343334). 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.
