Description

This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 181 of the TRDN protein (p.Glu181Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TRDN-related conditions. 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 TRDN protein function with a negative predictive value of 80%. 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.
