Invitae RCV000801797 SCV000941593 uncertain significance Mucopolysaccharidosis, MPS-III-B; Charcot-Marie-Tooth disease axonal type 2V 2022-09-12 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 152 of the NAGLU protein (p.Arg152Gln). This variant is present in population databases (rs141018386, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with NAGLU-related conditions. ClinVar contains an entry for this variant (Variation ID: 647311). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
