Labcorp Genetics (formerly Invitae), Labcorp RCV003085362 SCV003461426 uncertain significance Peroxisome biogenesis disorder 2025-01-13 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 379 of the PEX6 protein (p.Arg379Trp). This variant is present in population databases (no rsID available, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PEX6-related conditions. ClinVar contains an entry for this variant (Variation ID: 2152848). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt PEX6 protein function with a negative predictive value of 95%. 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.
