Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 4P and 1B. PM1PM2BP4
The NM_000546.6(TP53):c.1115A>G(p.Lys372Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign 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. K372T) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2Benign:1
Uncertain significance, criteria provided, single submitter | clinical testing | Genome-Nilou Lab | Jun 18, 2022 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Dec 09, 2019 | This missense variant replaces lysine with arginine at codon 372 of the TP53 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. Experimental functional studies have demonstrated that methylation of Lys372 regulates protein stability and that this variant (p.Lys372Arg) abolishes this effect (PMID 15525938, 17108971), however other studies have shown this variant to be functional in transactivation studies (PMID 12826609, 30224644). To our knowledge, this variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 07, 2021 | 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. - |

TP53-related condition Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | PreventionGenetics, part of Exact Sciences | Aug 14, 2023 | The TP53 c.1115A>G variant is predicted to result in the amino acid substitution p.Lys372Arg. Methylation studies suggest this variant impacts protein stability (Figures 1E and 4E, Chuikov et al. 2004. PubMed ID: 15525938; Figure 1, Huang et al. 2006. PubMed ID: 17108971). It has also been reported in a mutagenesis study (Table S2 and S3, Giacomelli et al. 2018. PubMed ID: 30224644). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. It has conflicting interpretations of likely benign and uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/230970/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
