Laboratory of Diagnosis and Therapy of Lysosomal Disorders, University of Padova RCV000677498 SCV000803008 uncertain significance Mucopolysaccharidosis type 6 2018-01-01 criteria provided, single submitter curation Absent from GnomAD (PM2
Invitae RCV000677498 SCV004293746 pathogenic Mucopolysaccharidosis type 6 2023-04-06 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects ARSB function (PMID: 8116615). 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 expected to disrupt ARSB protein function. ClinVar contains an entry for this variant (Variation ID: 559723). This missense change has been observed in individual(s) with mucopolysaccharidosis type VI (PMID: 8116615, 10923267, 24373060). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces cysteine, which is neutral and slightly polar, with tyrosine, which is neutral and polar, at codon 521 of the ARSB protein (p.Cys521Tyr).
