Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1PM2BP6
The NM_000546.6(TP53):c.649G>T(p.Val217Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,882 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. V217M) has been classified as Likely benign.

Submissions by phenotype
Li-Fraumeni syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 11, 2023 | This variant is not present in population databases (gnomAD 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. Experimental studies have shown that this missense change does not substantially affect TP53 function (PMID: 12826609, 29979965, 30224644). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is not expected to disrupt TP53 function. ClinVar contains an entry for this variant (Variation ID: 1386154). This variant has not been reported in the literature in individuals affected with TP53-related conditions. This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 217 of the TP53 protein (p.Val217Leu). - |
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 22, 2020 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
