Labcorp Genetics (formerly Invitae), Labcorp RCV002651786 SCV003525405 uncertain significance Mucopolysaccharidosis type 1 2022-07-14 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 84 of the IDUA protein (p.Gly84Ala). This variant is present in population databases (no rsID available, gnomAD 0.001%). This missense change has been observed in individual(s) with a positive newborn screening result for IDUA-related disease (PMID: 28721335). 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. 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.
