Invitae RCV000699966 SCV000828699 uncertain significance Mucopolysaccharidosis, MPS-III-B; Charcot-Marie-Tooth disease axonal type 2V 2022-07-09 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 190 of the NAGLU protein (p.Asn190Ser). This variant is present in population databases (rs375458666, gnomAD 0.007%). 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: 577264). 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 not expected to disrupt NAGLU protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
Preventiongenetics, part of Exact Sciences RCV003411631 SCV004113844 uncertain significance NAGLU-related condition 2023-04-03 criteria provided, single submitter clinical testing The NAGLU c.569A>G variant is predicted to result in the amino acid substitution p.Asn190Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-40690394-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
