Invitae RCV000699966 SCV000828699 uncertain significance Mucopolysaccharidosis, MPS-III-B; Charcot-Marie-Tooth disease, axonal type 2V 2018-07-16 criteria provided, single submitter clinical testing This sequence change replaces asparagine with serine at codon 190 of the NAGLU protein (p.Asn190Ser). The asparagine residue is weakly conserved and there is a small physicochemical difference between asparagine and serine. This variant is present in population databases (rs375458666, ExAC 0.01%). This variant has not been reported in the literature in individuals with NAGLU-related disease. 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: "Benign"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
