ClinGen TP53 Variant Curation Expert Panel,ClinGen RCV000463420 SCV001142550 pathogenic Li-Fraumeni syndrome 2019-08-28 reviewed by expert panel curation This variant is within a codon that is an established hotspot in the TP53 gene (PM1; PMID: 2046748). This variant has a BayesDel score > 0.16 and Align GVGD (Zebrafish) is Class 15 or higher (PP3). Transactivation assays show a low functioning allele according to Kato, et al. and there is evidence of a dominant negative effect and loss of function according to Giacomelli, et al. (PS3; PMID: 12826609, 30224644). This variant has been reported in at least 2 probands meeting classic Li-Fraumeni syndrome criteria and 4 probands meeting Chompret criteria (PS4; PMID: 16401470, 15390294, 9242456, 10864200, 1565144, 7732013). Additionally, there is a de novo observation of a proband with breast cancer at age 29 with parental confirmation (PS2; PMID: 12672316). In summary, TP53 c.818G>A; p.Arg273His meets criteria to be classified as pathogenic for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: PM1, PP3, PS3, PS4, PS2.

Ambry Genetics RCV000115738 SCV000186052 pathogenic Hereditary cancer-predisposing syndrome 2018-08-17 criteria provided, single submitter clinical testing ​The p.R273H pathogenic mutation (also known as c.818G>A), located in coding exon 7 of the TP53 gene, results from a G to A substitution at nucleotide position 818. The arginine at codon 273 is replaced by histidine, an amino acid with highly similar properties. This alteration occurs at a well-characterized mutation "hotspot" located within the functionally critical DNA binding domain, and is associated with a classic LFS-associated tumor spectrum, including soft tissue and osteosarcomas, breast cancer, and central nervous system malignancies (Petitjean A et al. IARC TP53 database [version R16, November 2012]. Hum. Mutat. 2007 Jun;28(6):622-9). To date, the p.R273H mutation has been detected in numerous individuals/families satisfying classic criteria for LFS and has segregated with disease in all families with multiple informative relatives tested (Ambry internal data). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
Invitae RCV000463420 SCV000545317 pathogenic Li-Fraumeni syndrome 2020-09-24 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 273 of the TP53 protein (p.Arg273His). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs28934576, ExAC 0.05%). This variant has been observed in numerous individuals and families with Li-Fraumeni syndrome (LFS) or Li-Fraumeni-associated cancers, and has been shown to segregate with disease in affected families (PMID: 9242456, 21484931, 17540308, 1565144, 20693561, 21552135). ClinVar contains an entry for this variant (Variation ID: 12366). This variant is located in the DNA-binding domain of the TP53 protein and is defined as a contact mutation that eliminates an essential DNA contact (PMID: 20516128). A mutant mouse model for this variant develops a variety of tumors and carcinomas by recapitulating LFS (PMID: 15607980). In addition, experimental studies have shown that this variant disrupts transcriptional activity in yeast-based assays (PMID: 12826609) and enhances cell proliferation, invasion, migration, and drug resistance in vitro (PMID: 17636407, 24677579). For these reasons, this variant has been classified as Pathogenic.

This variant was found in 3/114148 control chromosomes at a frequency of 0.0000263, which does not exceed the estimated maximal expected allele frequency of a pathogenic TP53 variant (0.0000398). The variant has been reported in numerous affected individuals in the literature and the codon location is a known hotspot mutation occurring as a frequent mutation in affected individuals. Functional studies report a dominant negative affect of the variant. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.
GeneKor MSA RCV000115738 SCV000821786 likely pathogenic Hereditary cancer-predisposing syndrome 2020-01-01 criteria provided, single submitter clinical testing This sequence change replaces Arginine with Histidine at codon 273 of the TP53 protein. The arginine residue is highly conserved among species and is located in a functional domain of the protein which interacts with multiple proteins. There is a large physiochemical difference between arginine and histidine (Grantham Score 29). There is a large physiochemical difference between arginine and tryptophan (Grantham Score 101).This variant is present in population databases at a very low frequency ( rs28934576, ExAC 0.02%) and has been reported in multiple individuals and families affected with Li-Fraumeni and Li-Fraumeni-like syndromes (PMID: 17540308, 1565144, 20693561). Algorithms developed to predict the effect of missense changes on protein structure and function suggest that this variant is likely to be damaging to the protein. In addition, experimental studies have shown that this variant affects TP53 transactivation activity at variable levels(PMID: 12826609). In summary, this is a rare sequence change that is expected to affect the TP53 protein and cause disease.The mutation database Clinvar contains entries for this variant (Variation ID: 12366)

Color Health, Inc RCV000115738 SCV001735236 pathogenic Hereditary cancer-predisposing syndrome 2021-01-12 criteria provided, single submitter clinical testing This missense variant replaces arginine with histidine at codon 273 in the DNA binding domain of the TP53 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). Functional studies have shown the mutant protein to be non-functional in transactivation assays (IARC database, PMID: 12826609, 20407015, 25584008) and cell growth assays (PMID: 24677579, 25584008, 29979965, 30224644). This variant has been reported in individuals affected with classic Li-Fraumeni syndrome (PMID: 1565144, 7732013, 10864200, 15390294, 16401470, 27374712) and in individuals meeting the Chompret criteria for Li-Fraumeni syndrome (PMID: 9242456, 25584008, 25787918). This variant has been identified in 4/251054 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Pathogenic.

Department of Pathology and Laboratory Medicine,Sinai Health System RCV001358389 SCV001554107 pathogenic Malignant tumor of breast no assertion criteria provided clinical testing The TP53 p.Arg273His variant was identified in 2 of 942 proband chromosomes (frequency: 0.002) from individuals or families with Li Fraumeni Syndrome or thyroid cancer (Masciari 2011, Romei 2017) and reported in multiple case studies in individuals or families with Li-Fraumeni Syndrome (Bemis 2007, Sugawara 2011, Baumuller 2010). In addition, the variant was reported as a somatic mutation in breast cancer, colorectal cancer, non-small cell lung cancer or high-grade glioma tissues (Jiang 2018, Heath-2018, Li 2018). The variant was also identified in dbSNP (ID: rs28934576) as "With Pathogenic allele", ClinVar (classified as pathogenic by Invitae, GeneDx, Ambry Genetics and eight other submitters; as likely pathogenic by two submitters), and in LOVD 3.0 (2x as pathogenic). The variant was identified in control databases in 4 of 245868 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European in 3 of 111470 chromosomes (freq: 0.00003), Ashkenazi Jewish in 1 of 9842 chromosomes (freq: 0.0001), but not in the African, Other, Latino, East Asian, Finnish, or South Asian populations. Several functional studies suggests the variant enhances cell migration, invasion abilities, influences apoptosis, leads to more aggressive phenotypes, and enhances cancer cell malignancy (Kang 2018, Joerger 2010, Dong 2007, Li 2014). The p.Arg273 residue is conserved across mammals and other organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein. The variant occurs outside of the splicing consensus sequence and 3 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing. In summary, based on the above information this variant meets our laboratory’s criteria to be classified as pathogenic.
