Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4BS2_SupportingBS3

This summary comes from the ClinGen Evidence Repository: Transactivation assays show retained function according to Kato, et al (PMID:12826609) and there is no evidence of a dominant negative effect or loss of function according to Giacomelli et al. (PMID:30224644) and Kotler et al. (PMID:29979965) (BS3). Additionally, this variant has a BayesDel score < 0.16 and Align GVGD (Zebrafish) is Class C15 (BP4). This variant has been observed in 2-7 60+ year old females without a cancer diagnosis (BS2_Supporting; internal laboratory contributors). In summary, TP53 c.868C>T; p.Arg290Cys meets criteria to be classified as Likely Benign for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: BS3; BP4; BS2_supporting. LINK:https://erepo.genome.network/evrepo/ui/classification/CA001448/MONDO:0007903/009

Genes affected
TP53 (HGNC:11998): (tumor protein p53) This gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants (PMIDs: 12032546, 20937277).
