TP53 VCEP
The NM_000546.6: c.188C>T variant in TP53 is a missense variant predicted to cause substitution of Alanine by Valine at amino acid 63 (p.Ala63Val). This variant has been observed in 2-3 heterozygous unrelated females from the same data source with no personal history of cancer prior to age 60 years and no personal history of sarcoma at any age (BS2_Supporting; Internal lab contributor: Invitae). In vitro assays performed in yeast and/or human cell lines showed functional transactivation and retained growth suppression activity indicating that this variant does not impact protein function (BS3; PMIDs: 12826609, 29979965, 30224644). Computational predictor scores (BayesDel = -0.099; Align GVGD Class C0) are below the recommended thresholds (BayesDel ≤ -0.008 and an Align GVGD Class ≤ 55), evidence that does not predict a damaging effect on TP53 via protein change. SpliceAI predicts that the variant has no impact on splicing. (BP4_Moderate). In summary, this variant meets the criteria to be classified as Benign for Li Fraumeni syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen TP53 VCEP: BS2_Supporting, BS3, BP4_Moderate. (Bayesian Points: -7; VCEP specifications version 2.1; 1/16/2025).

PM2
The highest population minor allele frequency in gnomAD v4.1.0 is 0.00004456 (2/44880 alleles) in the East Asian population (PM2, BS1, and BA1 are not met).
PM1
This variant does not reside within a region of TP53 that is defined as a mutational hotspot by the ClinGen TP53 VCEP (PM1 not met).
PM5
2 different missense variants (p.Ala63Gly, p.Ala63Thr) in the same codon have been reported (ClinVar Variation IDs: 229693, 231015). However, these variants have not yet met the criteria to be classified as pathogenic or likely pathogenic by the ClinGen TP53 VCEP’s specifications (PM5 not met).
