Description

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 11 of the TP53 protein (p.Glu11Lys). This variant is present in population databases (rs201382018, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with TP53-related conditions. ClinVar contains an entry for this variant (Variation ID: 418693). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is not expected to disrupt TP53 function with a negative predictive value of 97.5%. Experimental studies have shown that this missense change does not substantially affect TP53 function (PMID: 9207066, 12826609, 30224644). 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.
