Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP3_Strong
The NM_000546.6(TP53):c.515T>G(p.Val172Gly) 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 Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V172D) has been classified as Likely pathogenic.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 04, 2014 | The p.V172G variant (also known as c.515T>G), located in coding exon 4 of the TP53 gene, results from a T to G substitution at nucleotide position 515. The valine at codon 172 is replaced by glycine, an amino acid with dissimilar properties. While this variant has not been reported in the literature to date, an alteration at the same codon, p.V172F (c.514G>T), was reported as a severe deficiency allele after showing a residual transactivation activity of 7% compared to wild-type (Monti P et al. Mol Cancer Res. 2011 Mar;9(3):271-9). The p.V172G variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. To date, this alteration has been detected with an allele frequency of approximately 0.003% (greater than 37,000 alleles tested) in our clinical cohort (includes this individual). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of p.V172G remains unclear. - |
