Variant summary

Our verdict is Uncertain significance. The variant received -4 ACMG points: 1P and 5B. BP4 PS4_Supporting BS3

This summary comes from the ClinGen Evidence Repository: Transactivation assays show retained 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) This variant has a BayesDel score < 0.16 and Align GVGD (Zebrafish) is Class C0 (BP4). This variant has been reported in 2 probands meeting Revised Chompret criteria (PS4_Supporting; internal laboratory contributor). The TP53 VCEP allows classification of a variant as Likely Benign with two supporting benign evidence codes if there is only a single supporting pathogenic code. However, the group did not feel a classification of Likely Benign was appropriate for this variant at this time given that the BayesDel score is just below the VCEP threshold and considering the phenotypes reported in the families meeting Chompret criteria. In summary, the clinical significance of TP53 c.37C>T (p.Pro13Ser) is uncertain for Li-Fraumeni syndrome.

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).
