TP53 VCEP
The NM_000546.6: c.538G>A variant in TP53 is a missense variant predicted to cause substitution of glutamic acid by lysine at amino acid 180 (p.Glu180Lys). This variant has been reported in 12 unrelated families meeting Revised Chompret criteria and reported in 1 individual with a HER2+ breast cancer. Based on this evidence, this variant scores 7 total points meeting the TP53 VCEP phenotype scoring criteria of 4-7.5 points. (PS4; PMIDs: 35974385, 33178583, 25584008, 8118819; Internal lab contributors: SCV000629836.7, SCV000581143.5, SCV000292772.10). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). In vitro assays performed in yeast and/or human cell lines showed partially functional transactivation and loss of growth suppression activity indicating that this variant impacts protein function (PS3_Moderate; PMIDs: 12826609, 30224644, 29979965). Computational predictor scores (BayesDel = 0.262; Align GVGD = Class C55) 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). In summary, this variant meets the criteria to be classified as Likely Pathogenic for Li Fraumeni syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen TP53 VCEP: PS4; PM2_Supporting, PS3_Moderate; PP3. (Bayesian Points: 8; VCEP specifications version 2.0; 7/24/2024)

PM2_Supporting
This variant is absent from gnomAD v4.1.0 (PM2_Supporting).
PS4
This variant has been reported in 12 unrelated families meeting Revised Chompret criteria and reported in 1 individual with a HER2+ breast cancer. Based on this evidence, this variant scores 7 total points meeting the TP53 VCEP phenotype scoring criteria of 4-7.5 points. (PS4; PMIDs: 35974385, 33178583, 25584008, 8118819; Internal lab contributors: SCV000629836.7, SCV000581143.5, SCV000292772.10).
PP3
Computational predictor scores (BayesDel = 0.262; Align GVGD = Class C55) 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).
PS3_Moderate
In vitro assays performed in yeast and/or human cell lines showed partially functional transactivation and loss of growth suppression activity indicating that this variant impacts protein function (PS3_Moderate; PMIDs: 12826609, 30224644, 29979965).

PM5
2 different missense variants (c.540G>T, p.Glu180Asp and c.540G>C, p.Glu180Asp) in the same codon have been reported (ClinVar Variation IDs: 1521256, 1509915). However, the variants have not yet been curated to determine if they would be classified as pathogenic or likely pathogenic by the ClinGen TP53 VCEP’s specifications (PM5 not evaluated).
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).
