Invitae RCV000633387 SCV000754609 uncertain significance Li-Fraumeni syndrome 2017-12-22 criteria provided, single submitter clinical testing This sequence change replaces serine with phenylalanine at codon 90 of the TP53 protein (p.Ser90Phe). The serine residue is weakly conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with TP53-related disease. An experimental study in yeast has shown that this variant does not impair the transcriptional transactivation activity of the TP53 protein (PMID: 12826609). 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.
