TP53 VCEP
The NM_000546.6: c.1079G>C variant in TP53 is a missense variant predicted to cause substitution of glycine by alanine at amino acid 360 (p.Gly360Ala). 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, Internal lab contributor: SCV000185669.8). The filtering allele frequency is 0.0005306 in the African/African American population in gnomAD v4.1.0, which is higher than the ClinGen TP53 VCEP threshold (≥0.0003 but <0.001) for BS1, and therefore meets this criterion (BS1). Computational predictor scores (BayesDel = -0.3336; 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, BS1 BP4_Moderate. (Bayesian Points: -10; VCEP specifications version 2.0; 7/24/2024)
