Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Aug 03, 2022 | 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; Published functional studies demonstrate a damaging effect: impaired DNA binding and transcriptional activation (Malcikova et al., 2010; Kotler et al., 2018); Observed in individuals with TP53-related cancers (Toguchida et al., 1992; Gonzalez et al., 2009; Mannan et al., 2016; Kwong et al., 2020); This variant is associated with the following publications: (PMID: 21343334, 1565143, 17606709, 23031740, 30840781, 31105275, 19225112, 26585234, 20128691, 29979965, 22887876, 32475984, 15510160, 33087929, 30720243, 26911350, 33138793, 28975465, 19556618, 29070607, 32817165) - |
Pathogenic, criteria provided, single submitter | clinical testing | Quest Diagnostics Nichols Institute San Juan Capistrano | Sep 09, 2022 | The frequency of this variant in the general population, 0.000004 (1/251476 chromosomes, http://gnomad.broadinstitute.org), is uninformative in assessment of its pathogenicity. In the published literature, the variant has been reported in affected individuals with Li-Fraumeni syndrome (LFS) (PMIDs: 17606709 (2007), 23031740 (2012), 26911350 (2016), 28975465 (2017), and 32817165 (2020)). Functional studies demonstrated decreased DNA binding, transactivation activity, a dominant negative effect, and reduced solubility compared to wild type (PMIDs: 8633021 (1996), 20128691 (2010), 21343334 (2011), 29979965 (2018), 30224644 (2018), 32475984 (2020)). Three de novo cases have been identified (PMIDs: 1565143 (1992), 19556618 (2009), and 22887876 (2012)). Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Based on the available information, this variant is classified as pathogenic. - |

Hereditary cancer-predisposing syndrome Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 15, 2021 | The p.S241F pathogenic mutation (also known as c.722C>T), located in coding exon 6 of the TP53 gene, results from a C to T substitution at nucleotide position 722. The serine at codon 241 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This mutation has been identified in multiple individuals diagnosed during childhood with tumors belonging to the Li-Fraumeni syndrome tumor spectrum (Toguchida J et al. N. Engl. J. Med. 1992 May;326:1301-8; Gonzalez KD et al. J. Med. Genet. 2009 Oct;46:689-93; Osumi T et al. Pediatr Blood Cancer. 2012 Dec;59:1332-3; Renaux-Petel M et al. J Med Genet. 2018 03;55:173-180). This alteration has been observed in at least one individual with a personal and/or family history that is consistent with TP53-related disease (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 (Brachmann RK et al. Proc. Natl. Acad. Sci. U.S.A. 1996 Apr;93:4091-5; Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9; Malcikova J et al. Biol Chem. 2010 391:197-205). 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). Two other alterations at the same codon, p.S241C (c.722C>G) and p.S241A (c.721T>G), have been described to also have non-functional transactivation in yeast based assays (Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9) and to be deficient at growth suppression with 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 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). 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 alteration is interpreted as a disease-causing mutation. - |

Li-Fraumeni syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 17, 2023 | This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 241 of the TP53 protein (p.Ser241Phe). This variant is present in population databases (rs28934573, gnomAD 0.0009%). This missense change has been observed in individual(s) with clinical features of Li-Fraumeni (PMID: 1565143, 23031740). ClinVar contains an entry for this variant (Variation ID: 12359). 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, 20128691, 21343334, 26585234, 29979965, 30224644). This variant disrupts the p.Ser241 amino acid residue in TP53. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12826609, 23259501, 25584008, 28279309, 30224644). 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. - |
