Description

This variant has not been reported in the literature in individuals affected with TPRKB-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change results in a frameshift in the TPRKB gene (p.Lys150Ilefs*60). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 26 amino acid(s) of the TPRKB protein and extend the protein by 33 additional amino acid residues. 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 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.
