Variant summary: TP53 c.844C>G (p.Arg282Gly) results in a non-conservative amino acid change located in the 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 was absent in 251410 control chromosomes (gnomAD). c.844C>G has been reported in the literature in multiple individuals affected with Li-Fraumeni Syndrome (LFS) and tumors belonging to the LFS spectrum (e.g. Poli_2005, Bougeard_2008, Schrader_2016, Rana_2019, Ceyhan-Birsoy_2021). These data indicate that the variant is likely to be associated with disease. A different variant affecting the same codon has been classified as pathogenic by our lab (c.844C>T, p.R282W), supporting the critical relevance of codon 282 to TP53 protein function. Multiple publications also reported experimental evidence and demonstrated the variant to be non-functional based on transcriptional activity in yeast, and substantially affecting TP53 function in human cell lines (e.g. Kato_2003, Monti_2011, Giacomelli_2018). The following publications have been ascertained in the context of this evaluation (PMID: 30224644, 15850016, 18511570, 26556299, 31105275, 34240179, 12826609). ClinVar contains an entry for this variant (Variation ID: 140821). Based on the evidence outlined above, the variant was classified as pathogenic. (less)

Published functional studies demonstrate a damaging effect: non-functional transactivation and loss of growth suppression activity (Monti et al., 2003; Ferrone et al., 2006; Giacomelli et al., 2018; Kotler et al., 2018); Observed in individuals with TP53-related tumors (Bougeard et al., 2015; Pelttari et al., 2017; Rana et al., 2019; Gao et al., 2020); Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 21343334, 22672556, 21761402, 21059199, 26619011, 25584008, 29979965, 11370630, 16818505, 12826609, 21305319, 12917626, 30224644, 1565144, 15850016, 23246812, 19468865, 17606709, 1565143, 15510160, 26556299, 30840781, 31105275, 32817165, 26014290, 22768918, 30720243, 28802053, 25847421) (less)

The p.R282G pathogenic mutation (also known as c.844C>G), located in coding exon 7 of the TP53 gene, results from a C to G substitution at nucleotide position 844. The arginine at codon 282 is replaced by glycine, an amino acid with dissimilar properties. This mutation is in the DNA binding domain of the p53 protein and is reported to have loss of transactivation capacity and predicted to affect several p53 isoforms (IARC TP53 database; 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 (Kotler E et al. Mol.Cell, 2018 Jul;71:178-190.e8; Giacomelli AO et al. Nat. Genet., 2018 Oct;50:1381-1387). It was previously identified in a patient with primary orbital liposarcoma whose family met diagnostic criteria for Li-Fraumeni syndrome (LFS) (Poli T et al. Tumori; 91:96-100). 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). Other variant(s) at the same codon, p.R282Q and p.R282W, have been identified in individual(s) with features consistent with Li-Fraumeni syndrome (Chompret et al. 2000 British J Cancer 82(12):1932-1937; Heyman et al. 2010 Radiation Oncology 5:104; Wu et al. 2011 Hum Genet 129:663-673). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this variant is interpreted as a disease-causing mutation. (less)

This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 282 of the TP53 protein (p.Arg282Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of Li-Fraumeni Syndrome (PMID: 15850016, 26014290, 26556299, 28802053). ClinVar contains an entry for this variant (Variation ID: 140821). 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, 21343334, 23246812, 29979965, 30224644). This variant disrupts the p.Arg282 amino acid residue in TP53. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1565143, 1565144, 11370630, 12826609, 17606709, 19468865, 21305319, 21761402, 22672556, 25584008). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. (less)
