Invitae RCV000459465 SCV000545348 uncertain significance Li-Fraumeni syndrome 2018-11-13 criteria provided, single submitter clinical testing This sequence change replaces proline with alanine at codon 151 of the TP53 protein (p.Pro151Ala). The proline residue is highly conserved and there is a small physicochemical difference between proline and alanine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be de novo in an individual affected with adrenocortical carcinoma (PMID: 29070607), and it has also been reported in an individual with breast cancer (PMID: 21761402). ClinVar contains an entry for this variant (Variation ID: 376641). An experimental study in yeast has shown that this variant impairs the transcriptional transactivation activity of the TP53 protein (PMID: 12826609). This missense change is also located within the DNA-binding domain of the TP53 protein where a significant number of previously reported TP53 missense variants have been found (PMID: 12826609, 26205489, 23355100). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant disrupts the p.Pro151 amino acid residue in TP53. Other variant(s) that disrupt this residue have been observed in affected individuals (PMID: 7881428, 17606709, 25584008, 20522432, 11479205, 25503501), suggesting that it is a clinically significant residue. As a result, variants that disrupt this residue are likely to be causative of disease. 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.
