ClinGen TP53 Variant Curation Expert Panel, ClinGen	RCV001527089	SCV001737928	pathogenic	Li-Fraumeni syndrome 1	2020-09-04	reviewed by expert panel	curation	The p.R213fs variant is predicted to result in a premature stop codon that leads to a truncated or absent protein (PVS1). This variant is absent in the gnomAD cohort (PM2_Supporting; http://gnomad.broadinstitute.org). This variant has been reported in 2 probands meeting Chompret criteria (PS4_Supporting; PMID: 11370630, NIH). In summary, TP53 c.636del (p.R213fs) meets criteria to be classified as pathogenic for Li-Fraumeni syndrome. ACMG/AMP criteria applied, as specified by the TP53 Variant Curation Expert Panel: PVS1, PM2_Supporting, PS4_Supporting.

Labcorp Genetics (formerly Invitae), Labcorp	RCV001853261	SCV002221571	pathogenic	Li-Fraumeni syndrome	2021-11-17	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Arg213Aspfs*34) in the TP53 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TP53 are known to be pathogenic (PMID: 20522432). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 218342). This premature translational stop signal has been observed in individual(s) with Li-Fraumeni syndrome (PMID: 11370630). This variant is not present in population databases (gnomAD no frequency).
Ambry Genetics	RCV002363022	SCV002658063	pathogenic	Hereditary cancer-predisposing syndrome	2020-03-04	criteria provided, single submitter	clinical testing	The c.636delT pathogenic mutation, located in coding exon 5 of the TP53 gene, results from a deletion of one nucleotide at nucleotide position 636, causing a translational frameshift with a predicted alternate stop codon (p.R213Dfs*34). This mutation has previously been reported in a family from a cohort of families fulfilling Chompret critiera and families suggestive of Li Fraumeni syndrome (Bougeard et al. 2008 J Med Genet 45(8):535-8 Supplementary Data). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
