Labcorp Genetics (formerly Invitae), Labcorp	RCV001390630	SCV001592426	pathogenic	Li-Fraumeni syndrome	2023-03-03	criteria provided, single submitter	clinical testing	This sequence change replaces cysteine, which is neutral and slightly polar, with glycine, which is neutral and non-polar, at codon 238 of the TP53 protein (p.Cys238Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with personal and/or family history of TP53-related cancer (PMID: 15925506, 30630526). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 376577). 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. Experimental studies have shown that this missense change affects TP53 function (PMID: 12826609, 21343334). This variant disrupts the p.Cys238 amino acid residue in TP53. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12826609, 19681600, 20407015, 21343334, 25294809, 25691460, 29470806). 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.
Ambry Genetics	RCV002365460	SCV002665477	pathogenic	Hereditary cancer-predisposing syndrome	2022-02-23	criteria provided, single submitter	clinical testing	The p.C238G pathogenic mutation (also known as c.712T>G), located in coding exon 6 of the TP53 gene, results from a T to G substitution at nucleotide position 712. The cysteine at codon 238 is replaced by glycine, an amino acid with highly dissimilar properties. 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). This mutation has been detected in a family meeting LFS criteria (Krutilkova V et al. Eur J Cancer, 2005 Jul;41:1597-603). 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.
