Genes affected

ARSB (HGNC:714): (arylsulfatase B) Arylsulfatase B encoded by this gene belongs to the sulfatase family. The arylsulfatase B homodimer hydrolyzes sulfate groups of N-Acetyl-D-galactosamine, chondriotin sulfate, and dermatan sulfate. The protein is targeted to the lysozyme. Mucopolysaccharidosis type VI is an autosomal recessive lysosomal storage disorder resulting from a deficiency of arylsulfatase B. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Dec 2016]

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 02, 2023	This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 144 of the ARSB protein (p.Gly144Arg). This variant is present in population databases (rs746206847, gnomAD 0.004%). This missense change has been observed in individual(s) with mucopolysaccharidosis type VI (PMID: 8116615, 16435196, 26909334, 30982216). ClinVar contains an entry for this variant (Variation ID: 559783). 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 with a positive predictive value of 95%. Experimental studies have shown that this missense change affects ARSB function (PMID: 8116615). For these reasons, this variant has been classified as Pathogenic. -
