Labcorp Genetics (formerly Invitae), Labcorp RCV002651788 SCV003525482 uncertain significance Mucopolysaccharidosis type 1 2022-04-26 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 265 of the IDUA protein (p.Gly265Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of mucopolysaccharidosis type I (PMID: 28752568). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.
