Description

This variant is not present in population databases (ExAC no frequency). 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. An experimental study in yeast has shown that this variant impairs the transcriptional transactivation activity of the TP53 protein (PMID: 12826609). This variant has not been reported in the literature in individuals with TP53-related conditions. This sequence change replaces proline with leucine at codon 60 of the TP53 protein (p.Pro60Leu). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and leucine.
