Variant summary
Our verdict is Benign. The variant received -6 ACMG points: 0P and 6B. BP4BS3BS2_Supporting
This summary comes from the ClinGen Evidence Repository: 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). LINK:https://erepo.genome.network/evrepo/ui/classification/CA000063/MONDO:0018875/009
