RCV001977240 | SCV002262978 | uncertain significance | Mucopolysaccharidosis type 1 | 2020-11-24 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals with IDUA-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces arginine with tryptophan at codon 459 of the IDUA protein (p.Arg459Trp). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and tryptophan. |
