This variant is denoted TP53 c.188C>T at the cDNA level, p.Ala63Val (A63V) at the protein level, and results in the change of an Alanine to a Valine (GCT>GTT). This variant is reported as having functional transactivation in the International Agency for Research on Cancer TP53 database based on functional assays by Kato et al. (2003). TP53 Ala63Val was not observed at a significant allele frequency in large population cohorts (Lek 2016). Since Alanine and Valine share similar properties, this is considered a conservative amino acid substitution. TP53 Ala63Val occurs at a position that is not conserved and is located in the SH3 Domain (Bode 2004). In silico analyses predict that this variant is unlikely to alter protein structure or function. Based on currently available information, it is unclear whether TP53 Ala63Val is pathogenic or benign. We consider it to be a variant of uncertain significance.
