Labcorp Genetics (formerly Invitae), Labcorp RCV000677499 SCV001583435 pathogenic Mucopolysaccharidosis type 6 2023-07-13 criteria provided, single submitter clinical testing This sequence change results in a frameshift in the ARSB gene (p.Thr526Metfs*48). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 8 amino acid(s) of the ARSB protein and extend the protein by 39 additional amino acid residues. This variant is not present in population databases (gnomAD no frequency). This frameshift has been observed in individual(s) with mucopolysaccharidosis type VI (PMID: 8116615, 24677745). ClinVar contains an entry for this variant (Variation ID: 559724). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this frameshift affects ARSB function (PMID: 8116615). For these reasons, this variant has been classified as Pathogenic.
