Pathogenic, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Apr 27, 2017 | The TP53 c.844C>T (p.Arg282Trp) variant is listed as a common somatic and germline variant in the IARC TP53 variant database (Arcand et al. 2015; Wassermann et al. 2015). Across a selection of the available literature the TP53 c.844C>T (p.Arg282Trp) variant has been identified in at least nine individuals with different types of cancer, all in a heterozygous state (Toguchida et al. 1992; Malkin et al. 1992; Audrezet et al. 1996; Prochazkova et al. 2009; Pinto et al. 2009; Melhem-Bertrandt et al. 2012; Sokolenko et al. 2015). The p.Arg282Trp variant has also been found in a heterozygous state in at least two asymptomatic family members. The variant was absent from 200 control individuals and is reported at a frequency of 0.0002 in the European American population of the Exome Sequencing Project. This frequency is based on two alleles in a region of good coverage so the variant is presumed to be rare. Functional studies using the p.Arg282Trp variant protein document that the variant destabilizes the protein, increases aggregation and alters signalling to increase cellular invasion (Zhang et al. 2016). Based on the collective evidence, the p.Arg282Trp variant is classified as pathogenic for Li-Fraumeni syndrome. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. - |

Pathogenic, criteria provided, single submitter | clinical testing | Neuberg Centre For Genomic Medicine, NCGM | - | The missense variant p.R282W in TP53 (NM_000546.6) has been reported in multiple affected patients (Mannan AU et al; Siraj AK et al). Functional studies suggest a damaging effect (Zerdoumi Y et al). The variant has been submitted to ClinVar as Pathogenic. The p.R282W variant is observed in 1/1,13,728 (0.0009%) alleles from individuals of European (Non-Finnish) background in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The p.R282W missense variant is predicted to be damaging by both SIFT and PolyPhen2. The arginine residue at codon 282 of TP53 is conserved in all mammalian species. The nucleotide c.844 in TP53 is predicted conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | KCCC/NGS Laboratory, Kuwait Cancer Control Center | Jul 07, 2023 | This sequence change replaces Arginine with Tryptophan at codon 282 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. This variant is present in population databases at a very low frequency ( rs28934574, ExAC 0.02%) and has been reported in multiple individuals and families affected with Li-Fraumeni and Li-Fraumeni-like syndromes (PMID: 25584008, 21305319, 21761402, 1565143). 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. The mutation database ClinVar contains entries for this variant (Variation ID:12364). Therefore, this variant is considered as pathogenic. - |

Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 29, 2021 | The p.R282W pathogenic mutation (also known as c.844C>T), located in coding exon 7 of the TP53 gene, results from a C to T substitution at nucleotide position 844. The arginine at codon 282 is replaced by tryptophan, an amino acid with dissimilar properties. This pathogenic mutation has been reported in multiple individuals or families with Li-Fraumeni Syndrome (LFS) or LFS-like syndrome (Toguchida J et al. N. Eng. J. Med. 1992 May;326(20):1301-8; Melhem-Bertrandt A et al. Cancer. 2012 Feb;118(4):908-13; Kast K et al. BMC Cancer. 2012 Jun;12:217; Mannan AU et al. J. Hum. Genet. 2016 Jun;61:515-22; Siraj AK et al. Hum. Genet. 2017 11;136:1431-1444). In an analysis of data from the p53 germline mutation database, mutations at position R282 were shown to have an association with early onset bone cancers (Xu J et al. Sci. Rep. 2014;4:4223). 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). Based on the available evidence, this alteration is classified as a pathogenic mutation. - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Mar 15, 2022 | This missense variant replaces arginine with tryptophan at codon 282 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 that this variant causes reduced transactivation activity, dominant negative effect, and loss of function in human cell proliferation and growth suppression assays (PMID: 12826609, 15958617, 21343334, 29979965, 30224644). This variant has been reported in many individuals affected with breast cancer, Li-Fraumeni syndrome, and Li-Fraumeni-like syndrome meeting Chompret criteria, including several de novo cases (PMID: 8402598, 8425176, 11370630, 1565143, 16206219, 19468865, 21305319, 21761402, 22672556, 25584008, 25619955, 28975465, 30709381). This variant has been identified in 1/251410 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Based on the available evidence, this variant is classified as Pathogenic. - |
Likely pathogenic, criteria provided, single submitter | clinical testing | GeneKor MSA | Jan 01, 2020 | This sequence change replaces Arginine with Tryptophan at codon 282 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 tryptophan (Grantham Score 101).This variant is present in population databases at a very low frequency ( rs28934574, ExAC 0.02%) and has been reported in multiple individuals and families affected with Li-Fraumeni and Li-Fraumeni-like syndromes (PMID: 25584008, 21305319, 21761402, 1565143). 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. 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:12364). - |

Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 18, 2024 | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 282 of the TP53 protein (p.Arg282Trp). This variant is present in population databases (rs28934574, gnomAD 0.0009%). This missense change has been observed in individual(s) with Li-Fraumeni syndrome (LFS) or Li-Fraumeni-like syndrome (PMID: 1565143, 1565144, 11370630, 21305319, 21761402, 25584008). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 12364). Advanced modeling performed at Invitae incorporating data from internal and/or published 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, 17606709, 29979965, 30224644). For these reasons, this variant has been classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Nov 03, 2022 | The p.Arg282Trp variant in TP53 has been reported in at least 4 individuals with features of Li-Fraumeni syndrome (Wasseman 2015 PMID: 25584008, Wu 2011 PMID: 21305319, Melhem-Bertrandt 2012 PMID: 21761402,Toguchida 1992 PMID: 1565143) and in ClinVar (Variation ID 12364). It has also been identified in 1/68022 European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. The p.Arg282Trp variant is located in the DNA binding domain of the TP53 protein and in vitro functional assays support impact on protein function with loss of transactivation capacity and dominant negative effect, affecting several p53 isoforms (IARC TP53 database, Monti 2011 PMID: 21343334, Zerdoumi 2017 PMID: 28472496, Kato 2003 PMID: 12826609). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant Li-Fraumeni syndrome. ACMG/AMP criteria applied: PM1, PP3, PS3, PS4, PM2_Supporting. - |

Pathogenic, criteria provided, single submitter | clinical testing | Genetic Services Laboratory, University of Chicago | Aug 08, 2018 | DNA sequence analysis of the TP53 gene demonstrated a sequence change, c.844C>T, in exon 8 that results in an amino acid change, p.Arg282Trp. The p.Arg282Trp change affects a highly conserved amino acid residue located in a domain of the TP53 protein that is known to be functional. The p.Arg282Trp substitution appears to be deleterious using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). This sequence change has been described in the EXAC database with a low population frequency of 0.002% (dbSNP rs28934574). The p.Arg282Trp pathogenic sequence change has previously been described in multiple unrelated individuals with Li-Fraumeni syndrome or Li-Fraumeni-like syndrome, and has been observed in the de novo state in at least two affected individuals (Malkin et al., 1992; Bougeard et al., 2001; Pinto et al., 2009; Wu et al., 2011; Kast et al., 2012; Melhem-Bertrandt et al., 2012; Wasserman et al., 2015). Functional studies have provided evidence that the p.Arg282Trp sequence change has a dominant negative effect and leads to significantly reduced TP53 transcriptional activity in response to DNA damage (Zerdoumi et al., 2017). - |
