Invitae RCV001244047 SCV001417241 likely pathogenic Li-Fraumeni syndrome 2023-08-04 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this missense change affects TP53 function (PMID: 11920959, 12826609, 16861262, 18555592, 20407015, 22090360). 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. ClinVar contains an entry for this variant (Variation ID: 376569). This missense change has been observed in individual(s) with Li-Fraumeni syndrome, pleural mesothelioma and acute myeloid leukemia (PMID: 26554828, 27622479). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 176 of the TP53 protein (p.Cys176Phe).
Ambry Genetics RCV002348142 SCV002646578 pathogenic Hereditary cancer-predisposing syndrome 2023-07-20 criteria provided, single submitter clinical testing The p.C176F variant (also known as c.527G>T), located in coding exon 4 of the TP53 gene, results from a G to T substitution at nucleotide position 527. The cysteine at codon 176 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This alteration has been reported as a somatic mutation 164 times in various tumors, but not as a germline mutation by the IARC TP53 database (Petitjean A et al. IARC TP53 database [version R17, November 2013]. Hum. Mutat. 2007 Jun;28:622-9). Numerous functional assays conducted in yeast 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; Jordan JJ et al. Mol. Cancer Res., 2010 May;8:701-16). 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). 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 protein (Martin AC et al. Hum Mutat. 2002 Feb; 19(2):149-64). This alteration has been reported in a proband whose personal and family history met Chompret criteria (Ossa CA et al. Biomedica, 2016 Jun;36:182-7). Another alteration at this same codon, p.C176Y, has been detected in at least one individual with classic Li-Fraumeni syndrome (Ambry internal data). 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.
Myriad Genetics, Inc. RCV004022202 SCV004932956 likely pathogenic Li-Fraumeni syndrome 1 2024-02-14 criteria provided, single submitter clinical testing This variant is considered likely pathogenic. Functional studies indicate this variant impacts protein function [PMID: 23713777, 25294809, 29979965]. This variant is expected to disrupt protein structure [Myriad internal data].
