Criteria Specification Information

Criteria Specifications for this VCEP
Evidence submitted by expert panel
TP53 VCEP
Transactivation assays show a low functioning allele according to Kato, et al. and there is evidence of a dominant negative effect and loss of function according to Giacomelli, et al. (PS3; PMID: 12826609, 30224644). This variant has a BayesDel score > 0.16 and Align GVGD (Zebrafish) is Class 65 (PP3_Moderate). This variant has >10 observations as a somatic hotspot variant in tumors (PM1; cancerhotspots.org v(2)). This variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). In summary, TP53 c.396G>C (p.Lys132Asn) meets criteria to be classified as likely pathogenic for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: PS3, PP3_Moderate, PM1, PM2_Supporting.
Met criteria codes
PM1
Not in hot spot codon but seen in 30 tumor samples on cancerhotspots.org.
PM2_Supporting
Absent from population databases.
PP3_Moderate
aGVGD class C65 and BayesDel >0.16. Strength modified as described by VCEP.
PS3
Experimental studies show this variant to be non-functional (Kato 2003) and to demonstrate both dominant negative effect (DNE) and loss of function (LOF) (Dearth 2007, Giacomelli 2018 and Kotler 2018).
