Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2_SupportingPM5BP4_Moderate
The NM_000546.6(TP53):c.215C>T(p.Pro72Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD Genomes project. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict 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. P72A) has been classified as Uncertain significance.
Verdict is Uncertain_significance. Variant got 1 ACMG points.

|Uncertain significance, criteria provided, single submitter||clinical testing||Invitae||Sep 01, 2022||This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 72 of the TP53 protein (p.Pro72Leu). 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: 864652). 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. 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. -|
