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).

Color Diagnostics, LLC DBA Color Health
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This missense variant replaces glycine with valine at codon 325 of the TP53 protein. Computational prediction suggests that this variant may not impact protein structure and function. Experimental functional studies have shown this variant to behave as wild-type in transcriptional transactivation and human cell growth suppression assays (PMID: 12826609, 16007150, 17606709, 21343334, 29955864, 30224644, but has also shown moderate impact in DNA binding and apoptosis assays (PMID: 10629033, 20128691). This variant has been reported in an individual affected with non-Hodgkin lymphoma and colon cancer in the literature (PMID: 1565144) and in an individual with osteosarcoma (PMID: 32191290). This variant has been identified in 1/251420 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Significance: Likely benign
Review Status: criteria provided, single submitter

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. -

This missense variant replaces glycine with valine at codon 325 of the TP53 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Experimental functional studies have shown this variant to behave as wild-type in transcriptional transactivation and human cell growth suppression assays (PMID: 12826609, 16007150, 17606709, 21343334, 29955864, 30224644, but has also shown moderate impact in DNA binding and apoptosis assays (PMID: 10629033, 20128691). This variant has been reported in an individual affected with non-Hodgkin lymphoma and colon cancer in the literature (PMID: 1565144). This variant has been identified in 1/251420 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Collection Method: clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 325 of the TP53 protein (p.Gly325Val). This variant is present in population databases (rs121912659, gnomAD 0.0009%). This missense change has been observed in individual(s) with colon carcinoma, Li-Fraumeni syndrome, non-Hodgkin lymphoma, and/or osteosarcoma (PMID: 1565144, 29955864, 32191290). ClinVar contains an entry for this variant (Variation ID: 12367). Invitae Evidence Modeling incorporating data from in vitro experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is not expected to disrupt TP53 function with a negative predictive value of 97.5%. Experimental studies have shown that this missense change does not substantially affect TP53 function (PMID: 12826609, 16007150, 20128691, 21343334, 29955864, 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. -

Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; While most published functional studies demonstrate no damaging effect on normal tetramer formation, cell cycle, colony growth, apoptotic activities, some results are conflicting regarding DNA binding, and transactivation of p53 response elements (Aurelio 2000, Boutell 2004, Kato 2003, Kawaguchi 2005, Malcikova 2010, Monti 2011); Observed in an individual with non-Hodgkin lymphoma and colon cancer (Malkin 1992); This variant is associated with the following publications: (PMID: 20128691, 17606709, 12544295, 25105660, 10629033, 16007150, 30840781, 25525159, 15221755, 18025850, 21343334, 1565144, 12826609, 30352134, 30224644, 29955864) -
