Labcorp Genetics (formerly Invitae), Labcorp RCV005198739 SCV005837612 likely pathogenic Li-Fraumeni syndrome 2024-06-13 criteria provided, single submitter clinical testing This variant, c.1001_1006dup, results in the insertion of 2 amino acid(s) of the TP53 protein (p.Gly334_Arg335dup), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has been observed in individuals with clinical features of Li-Fraumeni syndrome (PMID: 18786442, 22233476, 22507745; Invitae). It has also been observed to segregate with disease in related individuals. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
