This sequence change replaces threonine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 214 of the TP53RK protein (p.Thr214Pro). This variant is present in population databases (rs746121007, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TP53RK-related conditions. ClinVar contains an entry for this variant (Variation ID: 1897600). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TP53RK protein function. 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. -
