ClinGen TP53 Variant Curation Expert Panel, ClinGen RCV000709407 SCV001429628 likely pathogenic Li-Fraumeni syndrome 2022-03-18 reviewed by expert panel curation 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV000709407 SCV000949001 likely pathogenic Li-Fraumeni syndrome 2023-03-19 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Lys132 amino acid residue in TP53. Other variant(s) that disrupt this residue have been observed in individuals with TP53-related conditions (PMID: 9157982, 18989156), which suggests that this may be a clinically significant amino acid residue. Experimental studies have shown that this missense change affects TP53 function (PMID: 12826609, 16861262, 29979965, 30224644). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is expected to disrupt TP53 function. ClinVar contains an entry for this variant (Variation ID: 376624). This missense change has been observed in individual(s) with breast cancer and/or clinical features of Li-Fraumeni syndrome (PMID: 32817165, 35264596; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 132 of the TP53 protein (p.Lys132Asn).
