This variant, c.482_487del, results in the deletion of 2 amino acid(s) of the TP53 protein (p.Ala161_Tyr163delinsAsp), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of Li-Fraumeni syndrome (Invitae). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant disrupts the p.Tyr163 amino acid residue in TP53. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 8164043, 18685109, 19556618, 12826609, 16861262). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
