Ambry Genetics RCV001025280 SCV001187441 pathogenic Hereditary cancer-predisposing syndrome 2019-12-05 criteria provided, single submitter clinical testing The p.S215I pathogenic mutation (also known as c.644G>T), located in coding exon 5 of the TP53 gene, results from a G to T substitution at nucleotide position 644. The serine at codon 215 is replaced by isoleucine, an amino acid with dissimilar properties. This variant is in the DNA binding domain of the TP53 protein and is reported to have loss of transactivation in yeast based assays (IARC TP53 database: Kato S et al. Proc. Natl. Acad. Sci. USA 2003 Jul;100:8424-9). Additional studies conducted in human cell lines indicate this alteration has a dominant negative effect and 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). Based on internal structural assessment, this alteration destabilized the DNA-binding domain (Cho Y et al. Science. 1994 Jul;265:346-55; Ambry internal data). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation.
Invitae RCV003509529 SCV004305354 uncertain significance Li-Fraumeni syndrome 2023-12-10 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 215 of the TP53 protein (p.Ser215Ile). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TP53-related conditions. ClinVar contains an entry for this variant (Variation ID: 376660). 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: 21232794). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
