RCV003065582 | SCV003458887 | uncertain significance | Mucopolysaccharidosis type 1 | 2022-08-19 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 648 of the IDUA protein (p.Pro648Ser). This variant is present in population databases (rs754403276, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with IDUA-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 IDUA protein function. 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. |
