Color Diagnostics, LLC DBA Color Health RCV001178315 SCV001342712 uncertain significance Hereditary cancer-predisposing syndrome 2020-03-23 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with glycine at codon 285 of the TP53 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). Functional studies have reported this variant to be partially active in yeast transactivation assay (IARC database and PMID: 12826609), functional in human cell proliferation assay (PMID: 29979965) and inconclusive in human cell growth suppression assay (PMID: 30224644). This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified 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.
Invitae RCV003509655 SCV004301821 uncertain significance Li-Fraumeni syndrome 2023-07-08 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 285 of the TP53 protein (p.Glu285Gly). 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: 919894). 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. 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.
