| Gene Variant Descriptions | TP53 G334R lies within the tetramerization domain of the Tp53 protein (PMID: 20978130). The functional effect of G334R is conflicting as it demonstrates Tp53 transactivation activity in a luciferase assay and suppresses colony formation in cell culture (PMID: 25584008), however, results in similar induction of MDM2 and p21 in one study but, in others, decreased transactivation of a subset of Tp53 target genes including p21, PUMA (PMID: 39520074), RRAD (PMID: 36749725), PADI4 (PMID: 37140445), PLTP (PMID: 36309086), PCLO, PLXNB3, and LCN15 with Nutlin treatment, decreased colony suppression (PMID: 32675277), increased half-life decreased interaction with Mdm2 (PMID: 39520074), and therefore, its effect on Tp53 protein function is unknown. |
