Criteria Specifications for this VCEP
Evidence submitted by expert panel
TP53 VCEP
The NM_000546.6: c.139C>T variant in TP53 is a missense variant predicted to cause substitution of Proline by Serine at amino acid 47 (p.Pro47Ser). The filtering allele frequency of the c.139C>T variant in the TP53 gene is 0.01560 for African/African American population by gnomAD v4.1.0, which is higher than the ClinGen TP53 VCEP threshold (≥0.001) for BA1, and therefore meets this criterion (BA1). 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: BA1 (Bayesian Points: N/A; VCEP specifications version 2.0; 7/24/2024).
Met criteria codes
BA1
The filtering allele frequency of the c.139C>T variant in the TP53 gene is 0.01560 for African/African American population by gnomAD v4.1.0, which is higher than the ClinGen TP53 VCEP threshold (≥0.001) for BA1, and therefore meets this criterion (BA1).
BS3
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 (PMIDs: 12826609, 29979965, 30224644) (BS3)
BS2
This variant has been observed in at least 8 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; FLOSSIES and Internal Lab Contributors: SCV000186571.8).
BP4
BP4_MODERATE. Computational predictor scores (BayesDel = -0.2146; 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)

PM5
3 different missense variants (c.140C>G; p.Pro47Arg, .139C>G; p.Pro47Ala, c.139C>A; p.Pro47Thr) in the same codon have been reported (ClinVar Variation ID 819145, 1721838, 406608). 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).
