Genes affected
TP53 (HGNC:11998): (tumor protein p53) This gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants (PMIDs: 12032546, 20937277).

The p.H179Y pathogenic mutation (also known as c.535C>T), located in coding exon 4 of the TP53 gene, results from a C to T substitution at nucleotide position 535. The histidine at codon 179 is replaced by tyrosine, an amino acid with similar properties. This mutation has been reported in the germline of multiple individuals with Li-Fraumeni syndrome (Lefrou L et al. Gastroenterol. Clin. Biol., 2006 Mar;30:484-6; Bougeard G et al. J. Clin. Oncol., 2015 Jul;33:2345-52; Zerdoumi Y et al. Hum. Mol. Genet., 2017 Jul;26:2591-2602). Numerous functional assays conducted in yeast and mammalian cells have shown the p.Y179H variant has decreased transactivation activity compared to wild type, and exerts a dominant negative effect (Kato S et al. Proc Natl Acad Sci USA. 2003 Jul 8;100(14):8424-9, Dearth LR et al. Carcinogenesis 2007 Feb; 28(2):289-98; Scian MJ et al. Oncogene, 2004 May;23:4430-43). Further functional studies indicate this mutation has oncogenic properties through upregulation of genes involved in cell cycle progression and proliferation (Ko JL et al. DNA Repair Amst; Yang D et al. Mol. Cell. Biochem., 2007 Oct;304:219-26; Scian MJ et al. Oncogene, 2004 May;23:4430-43). 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 alteration is located in the DNA binding domain, and is one of four residues necessary to bind the zinc molecule that stabilizes the beta sheet structure of the p53 protein (Martin AC et al. Hum. Mutat. 2002 Feb; 19(2):149-64). 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). In addition, another alteration at this same position, p.H179Q was identified as a de novo mutation in a patient with two Li-Fraumeni core cancers (Gonzalez KD et al. J. Med. Genet. 2009 Oct; 46(10):689-93). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

PS2_Moderate, PS3_Moderate, PM1, PM2_Supporting, PM5 c.535C>T, located in exon 5 of the TP53 gene, is predicted to result in the substitution of histidine by tyrosine at the hotspot codon 179, p.(His179Tyr). There are 41 reports of somatic occurrences for the same amino acid in cancerhotspots.org (PM1). It is not present in the population database gnomAD v2.1.1, non-cancer dataset (PM2_Supporting). This is a missense variant at an amino acid residue where a different missense variant (c.537T>A) was previously determined to be pathogenic according to the TP53 VCEP’s specifications (PM5). This variant is predicted pathogenic by BayesDel (score: 0.602) and is Class C65 at aGVGD. This variant was reported to be partially functional (PMID: 12826609) and to cause LOF (PMID: 30224644) in clinically calibrated functional assays (PS3_Moderate). This variant has been reported in the ClinVar database (4x pathogenic, 5x likely pathogenic), in the LOVD database (1x likely pathogenic). This variant has been identified as a de novo occurrence in an individual with LFS-strongly associated cancers (PS2_Moderate). It has been reported in multiple individuals with Li-Fraumeni-associated tumors (PMID: 28477316, 26014290, 28369373). Based on currently available information, the variant c.535C>T should be considered a likely pathogenic variant according to TP53 ClinGen EP specifications 2.2. -

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 179 of the TP53 protein (p.His179Tyr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with a personal and/or family history of Li-Fraumeni syndrome (PMID: 16633321, 18511570, 25433984). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 127815). 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: 11896595, 12509279, 12726864, 12826609, 17530187, 26497680). For these reasons, this variant has been classified as Pathogenic. -
