TP53 VCEP
The NM_000546.6: c.524G>A variant in TP53 is a missense variant predicted to cause substitution of arginine by histidine at amino acid 175 (p.Arg175His). This variant has been reported in 3 unrelated families meeting Classic and Revised Chompret criteria.Based on this evidence, this variant scores 2.5 total points meeting the TP53 VCEP phenotype scoring criteria of 2-3.5 points. (PS4_Moderate: 8825920, 11370630, 8164043). The variant has been reported to segregate with LFS-associated cancers in 5-6 meioses in 1 family (PP1_Moderate; PMID: 8825920). In vitro assays performed in yeast and/or human cell lines showed non-functional transactivation and loss of growth suppression activity indicating that this variant impacts protein function (PS3; PMIDs: 12826609, 30224644, 29979965). This variant resides within a codon (NM_00546.4: 175, 245, 248, 249, 273, 282) of TP53 that is defined as a mutational hotspot by the ClinGen TP53 VCEP (PM1; PMID: 8023157). Computational predictor scores (BayesDel = 0.54619; Align GVGD = Class C25) are above recommended thresholds (BayesDel > 0.16 and an Align GVGD Class of > 15), evidence that correlates with impact to TP53 via protein change (PP3). This variant has an allele frequency of 0.000005932 (7/1180032 alleles) in the European (non-Finnish) population in gnomAD v4.1.0 which is lower than the Clingen TP53 VCEP threshold (<0.00004) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). In summary, this variant meets the criteria to be classified as [CLASSIFICATION] for Li Fraumeni syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen TP53 VCEP: PS3, PP1_Moderate, PM1, PS4_Moderate, PP3, PM2_Supporting. (Bayesian Points: 12; VCEP specifications version 2.0; 9/6/2024)
