Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_000546.6(TP53):c.238C>T(p.Pro80Ser) 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P80L) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 14, 2017 | The p.P80S variant (also known as c.238C>T), located in coding exon 3 of the TP53 gene, results from a C to T substitution at nucleotide position 238. The proline at codon 80 is replaced by serine, an amino acid with similar properties. This alteration has been reported as a somatic mutation once but not as a germline mutation by the IARC TP53 database (Petitjean A et al. IARC TP53 database [version R17, November 2013]. Hum. Mutat. 2007 Jun;28:622-9). This variant is in the proline-rich domain of the TP53 protein and was not found to have an effect on transactivation capacity in yeast-based assays (IARC TP53 database; Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9). This amino acid position is highly conserved through mammals but not in all available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |

Li-Fraumeni syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jun 28, 2022 | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 80 of the TP53 protein (p.Pro80Ser). 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: 406593). Advanced modeling of experimental studies (such as gene expression, population dynamics, functional pathways, and cell-cycle effects in cell culture) performed at Invitae indicates that this missense variant is not expected to disrupt TP53 protein function. Experimental studies have shown that this missense change does not substantially affect 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. - |
