Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1PM2PM5PP3_StrongPP5
The NM_000546.6(TP53):c.658T>G(p.Tyr220Asp) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Y220C) has been classified as Pathogenic.

Li-Fraumeni syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 16, 2021 | 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. Experimental studies have shown that this missense change affects TP53 function (PMID: 12826609, 29979965, 30224644). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt TP53 protein function. ClinVar contains an entry for this variant (Variation ID: 376689). This variant has not been reported in the literature in individuals affected with TP53-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with aspartic acid at codon 220 of the TP53 protein (p.Tyr220Asp). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and aspartic acid. - |
