Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. BS3_SupportingPS4_SupportingPP3

This summary comes from the ClinGen Evidence Repository: This variant has a BayesDel score > 0.16 and Align GVGD (Zebrafish) is Class 15 or higher (PP3). This variant has been reported in 2 probands meeting Chrompret criteria (PS4_Supporting; PMID:25584008, internal laboratory contributor). Transactivation assays show partially functional variant 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_Supporting; PMID:12826609, 30224644). In summary, the clinical significance of TP53 c.800G>A (p.Arg267Gln) is uncertain for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Expert Panel: PP3, PS4_Supporting, BS3_Supporting. LINK:https://erepo.genome.network/evrepo/ui/classification/CA000424/MONDO:0018875/009

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).
