Description

This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with SUOX-related conditions. This variant disrupts a region of the SUOX protein in which other variant(s) (p.Arg459Gln) have been determined to be pathogenic (PMID: 31870341). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Trp283*) in the SUOX gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 263 amino acid(s) of the SUOX protein.
