GeneDx RCV000235730 SCV000293920 uncertain significance not provided 2016-02-05 criteria provided, single submitter clinical testing This variant is denoted TP53 c.698A>G at the cDNA level, p.His233Arg (H233R) at the protein level, and results in the change of a Histidine to an Arginine (CAC>CGC). Functional assays suggest that this variant may have a benign effect on protein function (Baroni 2004, Pekova 2011). TP53 His233Arg was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, suggesting it is not a common benign variant in these populations. Since Histidine and Arginine share similar properties, this is considered a conservative amino acid substitution. TP53 His233Arg occurs at a position that is conserved in mammals and is located in the DNA binding domain and a region of interaction with multiple proteins (Bode 2004, UniProt). In silico analyses predict that this variant is probably damaging to protein structure and function. Based on currently available evidence, it is unclear whether TP53 His233Arg is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
