Criteria Specification Information

Criteria Specifications for this VCEP
Evidence submitted by expert panel
TP53 VCEP
Transactivation assays show supertransactivation function according to Kato, et al. and there is no evidence of a dominant negative effect or loss of function according to Giacomelli, et al. (BS3; PMID: 12826609, 30224644). Additionally, this variant has a BayesDel score < 0.16 and Align GVGD (Zebrafish) is Class C0 or Class C15 (BP4). This variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). In summary, the clinical significance of TP53 c.886C>T (p.His296Tyr) is likely benign for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: BS3, BP4, PM2_Supporting.
