Invitae RCV000677597 SCV001586725 pathogenic Mucopolysaccharidosis type 6 2020-08-14 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with serine at codon 266 of the ARSB protein (p.Tyr266Ser). The tyrosine residue is highly conserved and there is a large physicochemical difference between tyrosine and serine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with mucopolysaccharidosis type VI (PMID: 22133300, 17458871). ClinVar contains an entry for this variant (Variation ID: 559814). 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. For these reasons, this variant has been classified as Pathogenic.
