The NM_000546.6: c.818G>A variant in TP53 is a missense variant predicted to cause substitution of arginine by histidine at amino acid 273 (p.R273H). This variant has been reported in numerous unrelated probands meeting Classic LFS and Revised Chompret criteria. Based on this evidence, this variant scores 8 total points meeting the TP53 VCEP phenotype scoring criteria of ≥ 8 points. (PS4_Very Strong; PMIDs, 16401470, 15390294, 9242456, 10864200, 1565144, 7732013; SCV000186052.8). This variant has been identified as a de novo occurrence with confirmed parental relationships in 1 individual with an LFS-associated cancer totaling 4 phenotype points (PS2; PMID: 1267231). At least two individuals with this variant were found to have a variant allele fraction of 5-25%, which is a significant predictor of variant pathogenicity (PP4_Moderate, PMID: 34906512, SCV000186052.8). This variant has an allele frequency of 0.00001186 (14/1179946 alleles) in the European (non-Finnish) population in gnomAD v4.1.0 which is lower than the Clingen TP53 VCEP threshold (<0.00004) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). In vitro assays performed in yeast and/or human cell lines showed non-functional transactivation and loss of growth suppression activity indicating that this variant impacts protein function (PS3; PMIDs: 12826609, 30224644, 29979965). This variant resides within a codon (NM_00546.4: 273) of TP53 that is defined as a mutational hotspot by the ClinGen TP53 VCEP (PM1; PMID: 8023157 ). Computational predictor scores (BayesDel = 0.52; Align GVGD = Class 25) are above recommended thresholds (BayesDel > 0.16 and an Align GVGD Class of > 15), evidence that correlates with impact to TP53 via protein change (PP3). In summary, this variant meets the criteria to be classified as pathogenic for Li Fraumeni Syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen TP53 VCEP: PS4_Very Strong, PS2, PM2_Supporting, PS3, PP4_Moderate, PM1, PP3. (Bayesian Points: 22; VCEP specifications version 2.0; 7/24/2024). (less)

DNA sequence analysis of the TP53 gene demonstrated a sequence change, c.818G>A, in exon 8 that results in an amino acid change, p.Arg273His. This sequence change has been described in the gnomAD database with a low global population frequency of 0.01% (dbSNP rs28934576). This pathogenic sequence change has previously been described in multiple patients and families with Li Fraumeni syndrome (PMIDs: 1565144, 21054160, 25584008). The p.Arg273His change affects a highly conserved amino acid residue located in a domain of the TP53 protein that is known to be functional. The p.Arg273 amino acid residue has multiple other amino acid substitutions that are reported to be pathogenic, including p.Arg273Leu, p.Arg273Gly, p.Arg273Ser, and p.Arg273Cys (PMIDs: 10864200, 8425176, 8164043, 8479749). Functional assays demonstrate that the p.Arg273His change results in deficient transactivation activity and results in a dominant negative effect over wild-type p53 (PMIDs: 12826609, 17636407). The p.Arg273His substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). (less)

The p.Arg273His variant in TP53 has been reported in at least 6 individuals with Li-Fraumeni syndrome and as a de novo occurence in an individual with breast cancer (selected publications Wong 2006 PMID: 16401470, Khayat 2004 PMID: 15390294, Varley 1997 PMID: 9242456, Chompret 2000 PMID: 10864200, Malkin 1992 PMID: 1565144, Flaman 1995 PMID: 7732013, Lalloo 2003 PMID: 12672316) and it was classified as pathogenic on August 28, 2019 by the ClinGen-approved ClinGen TP53 Variant Curation Expert Panel (Variation ID 12366). It has also been identified in 2/68014 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant is within a codon that is an established hotspot in the TP53 gene (Levine 1991 PMID: 2046748). Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In vitro transactivation assays show a low functioning allele and there is evidence of a dominant negative effect and loss of function (Kato 2003 PMID: 12826609, Giacomelli 2018 PMID: 30224644). In summary, the p.Arg273His meets criteria to be classified as pathogenic for autosomal dominant Li-Fraumeni syndrome. ACMG/AMP criteria applied: PM1, PP3, PS3, PS4, PS2, PM2_Supporting. (less)

This variant has been reported in individuals with LFS-associated cancers (PMID: 10645809, 10864200, 16401470, 22851211, 25787918, internal data). Computational evidence supports a deleterious effect of this variant on protein function. Transactivation assays show a low functioning allele according to Kato et al., and evidence of loss of function and a dominant negative effect according to Giacomelli et al. (PMID: 12826609, 30224644). This variant is a somatic hotspot variant in tumors according to the Cancer Hotspots database (cancerhotspots.org).

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). In addition, this alteration has been observed numerous times as a somatic mutation in the cancerhotspots.org database (Chang MT et al. Cancer Discov. 2018 02;8:174-183). To date, the p.R273H mutation has been detected in numerous individuals/families satisfying classic criteria for LFS (Ambry internal data). This variant is in the DNA binding domain of the TP53 protein and is reported to have non-functional transactivation in yeast based assays (Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9). Studies conducted in human cell lines indicate this alteration is deficient at growth suppression and has a dominant negative effect (Kotler E et al. Mol.Cell. 2018 Jul;71:178-190.e8; Giacomelli AO et al. Nat. Genet. 2018 Oct;50:1381-1387). This variant has been detected in at least one individual at an allele fraction that is suggestive of clonal hematopoiesis, a predictor of TP53 pathogenicity (Ambry internal data; Fortuno C et al. Genet Med. 2022 03;24:673-680). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this variant is interpreted as a disease-causing mutation. (less)

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. (less)

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) (less)

Comment:
The TP53 c.818G>A, p.Arg273His variant (rs28934576), has been reported in multiple patients diagnosed with Li-Fraumeni syndrome (Curry 2011, Khayat 2004, Malkin 1992, Park 2016, Schlegelberger … (more)
The TP53 c.818G>A, p.Arg273His variant (rs28934576), has been reported in multiple patients diagnosed with Li-Fraumeni syndrome (Curry 2011, Khayat 2004, Malkin 1992, Park 2016, Schlegelberger 2015, Siddiqui 2005, Tsaousis 2019, Zerdoumi 2012). Functional characterization of the variant protein indicates a defect in the transactivation of TP53 targets (Malcikova 2010, Monti 2007, Monti 2011, Zerdoumi 2012) and repression of genes involved in cell proliferation (Scian 2004). This results in an increase in growth, invasiveness, and resistance to apoptosis of cell lines upon DNA damage (Kalo 2012, Li 2014). This variant is found in the general population with an allele frequency of 0.0016% (4/251054 alleles) in the Genome Aggregation Database. The arginine at residue 273 is highly conserved, and computational analyses predict that this variant is deleterious (REVEL: 0.868). Based on the above information, the variant is classified as pathogenic. References: Curry S et al. Rhabdomyosarcoma-associated renal cell carcinoma: a link with constitutional Tp53 mutation.

The c.818G>A, p.Arg273His missense variant in TP53 has been reported in several individuals meeting classic Li-Fraumeni or Chompret criteria,occurring de novo in at least one individual and segregating with disease in affected families (PMID: 9242456, 21484931, 17540308, 1565144, 20693561, 21552135). 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 various 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). This variant has three heterozygous alleles in the gnomAD v3.1.1 database, suggesting it is not a common benign variant in the populations represented in this database. In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, this variant is classified as pathogenic.

The c.818G>A (p.Arg273His) variant of the TP53 gene replaces arginine with histidine at codon 273 of the TP53 protein. This variant has been reported in at least 2 probands meeting classic Li-Fraumeni syndrome criteria and 4 probands meeting Chompret criteria (PMID: 16401470, 15390294, 9242456, 10864200, 1565144, 7732013). Additionally, it has been observed as a de novo variant in a proband with breast cancer at age 29 (PMID: 12672316). This variant is within a codon that is an established mutational hotspot in the TP53 gene (PMID: 2046748). Functional studies have shown that the variant results in non-functional of the protein (PMID: 12826609) and evidence of a dominant negative effect and loss of function (PMID: 30224644). This variant has been identified in 4/251054 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Computational prediction suggests that this variant may have deleterious impact on protein structure and function (a BayesDel score > 0.16 and Align-GVGD is C25). Based on the supporting evidence, the c.818G>A (p.Arg273His) variant in TP53 is interpreted as pathogenic. (less)

Variant summary: TP53 c.818G>A (p.Arg273His) results in a non-conservative amino acid change located in the p53, DNA-binding domain of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 251054 control chromosomes. c.818G>A has been reported in the literature in multiple individuals affected with Li-Fraumeni Syndrome (Bougeard_2015, Varley_1997, Wasserman_2015). These data indicate that the variant is very likely to be associated with disease. A different variant affecting the same codon has been classified as pathogenic by our lab (c.817C>T, p.Arg273Cys), supporting the critical relevance of codon 273 to TP53 protein function. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in abolishing TP53 binding (Wasserman_2015) and functional inactiviation (Lang_2004). The following publications have been ascertained in the context of this evaluation (PMID: 25584008, 26014290, 9242456, 15607981). ClinVar contains an entry for this variant (Variation ID: 12366). Based on the evidence outlined above, the variant was classified as pathogenic. (less)

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 273 of the TP53 protein (p.Arg273His). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of Li-Fraumeni syndrome (LFS) (PMID: 1565144, 9242456, 17540308, 20693561, 21484931, 21552135). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 12366). Invitae Evidence Modeling incorporating data from in vitro experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is expected to disrupt TP53 function with a positive predictive value of 97.5%. Experimental studies have shown that this missense change affects TP53 function (PMID: 12826609, 29979965, 30224644). For these reasons, this variant has been classified as Pathogenic. (less)

Same nucleotide change resulting in same amino acid change has been previously reported to be associated with COL1A1 related disorder (ClinVar ID: VCV001687324 /PMID: 30143849).A different missense change at the same codon (p.Ala1387Val) has been reported to be associated with COL1A1 related disorder (ClinVar ID: VCV000041470 /PMID: 21834035). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. (less)

Malkin et al. (1992) identified a germline CGT-to-CAT mutation in exon 8 of the p53 gene that converted arg273 to his (R273H). The proband was a male in whom soft-tissue sarcoma was discovered at the age of 22 years and gastric carcinoma at the age of 30 years (see LFS; 151623). In 5 of 6 anaplastic carcinomas of the thyroid and in an anaplastic carcinoma thyroid cell line ARO, Fagin et al. (1993) identified the R273H mutation. The presence of p53 mutations almost exclusively in poorly differentiated thyroid tumors and thyroid cancer cell lines suggested that inactivation of p53 may confer these neoplasms with aggressive properties and may further loss of differentiated function.

Comment:
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 … (more)
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. (less)
