Labcorp Genetics (formerly Invitae), Labcorp RCV000794731 SCV000934157 uncertain significance Li-Fraumeni syndrome 2024-12-22 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with aspartic acid, which is acidic and polar, at codon 107 of the TP53 protein (p.Tyr107Asp). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TP53-related conditions. ClinVar contains an entry for this variant (Variation ID: 641482). Invitae Evidence Modeling incorporating data from in vitro experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is expected to disrupt TP53 function with a positive predictive value of 97.5%. Experimental studies have shown that this missense change affects TP53 function (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.
Myriad Genetics, Inc. RCV004027500 SCV004932345 likely pathogenic Li-Fraumeni syndrome 1 2024-02-12 criteria provided, single submitter clinical testing This variant is considered likely pathogenic. Functional studies indicate this variant impacts protein function [PMID: 29979965]. This variant is expected to disrupt protein structure [Myriad internal data].
