Labcorp Genetics (formerly Invitae), Labcorp RCV003509690 SCV004248552 pathogenic Li-Fraumeni syndrome 2023-06-06 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1319403). This variant has not been reported in the literature in individuals affected with TP53-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ile50Asnfs*2) 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).

deCODE genetics, Amgen RCV003485730 SCV004022265 likely pathogenic Li-Fraumeni syndrome 1 2023-07-21 no assertion criteria provided research The variant NM_000546.6:c.148dup (chr17:7676220) in TP53 was detected in 1 heterozygote out of 58K WGS Icelanders (MAF= 0,001%). This variant has not been reported in ClinVar previously. Based on ACMG criteria (PVS1, PM2) this variant classifies as likely pathogenic.
