Labcorp Genetics (formerly Invitae), Labcorp RCV001915782 SCV002180972 uncertain significance Mucopolysaccharidosis type 1 2023-11-20 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 223 of the IDUA protein (p.Asp223Tyr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IDUA-related conditions. ClinVar contains an entry for this variant (Variation ID: 1406350). 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 expected to disrupt IDUA protein function with a positive 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.
