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).

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Variant summary: TP53 c.466C>T (p.Arg156Cys) results in a non-conservative amino acid change located in the p53, DNA-binding domain (IPR011615) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251282 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.466C>T has been reported in the literature in individuals affected with breast cancer (Sun_2017, Sheng_2020, PMID 33471991), but it has also been reported in unaffected controls (PMID 33471991). These report(s) do not provide unequivocal conclusions about association of the variant with disease. The IARC database reports the variant as being partially-functional based on overall transcription activity (TA) on eight different promoters as measured in yeast assays by Kato et al (2003). However, multiple other studies using an array of different assays determined the variant to be functional (Kakudo_2005, Giacomelli_2018, Kotler_2018, Doffe_2021). Five ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance and three ClinVar submitters (evaluation after 2014) cite it as likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Published functional studies demonstrate retention of growth suppression and apoptotic activities, and partial or wildtype-like transcriptional activation (Kato 2003, Kakudo 2005, Kotler 2018); Observed in individuals with HER2-negative breast cancer (Sun 2017, Sheng 2019); This variant is associated with the following publications: (PMID: 12826609, 15781620, 23200980, 26068095, 28477877, 14559903, 28724667, 29979965, 25348012, 22983585, 28861920, 30871527, 30352134, 30840781, 28251968, 31119730) -

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

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 156 of the TP53 protein (p.Arg156Cys). This variant is present in population databases (rs563378859, gnomAD 0.003%). This missense change has been observed in individual(s) with breast cancer (PMID: 28724667). ClinVar contains an entry for this variant (Variation ID: 127810). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt TP53 protein function with a negative predictive value of 95%. Experimental studies have shown that this missense change does not substantially affect TP53 function (PMID: 12826609, 29979965, 30224644). 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. -
