Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000169649 SCV000221172 likely pathogenic Mucopolysaccharidosis type VI 2014-03-03 criteria provided, single submitter clinical testing The Arg484Gly variant in ARSB has been reported in a patient with mucopolysaccharidosis type VI who also carried a pathogenic variant in trans (compound heterozygous) (Karageorgos et al, 2004). The Arg484Gly variant has been identified in 0.046% (1/2178) of the 1000 Genomes population. However, the presence of this variant in trans configuration with a reported pathogenic variant in an individual with clinical features of mucopolysaccharidosis type VI, increases the likelihood that the Arg484Gly variant is pathogenic. In addition, ARSB protein was not detected by an immunologic quantification assay supporting a deleterious impact to protein function (Karageorgos et al, 2004). In summary, the Arg484Gly variant is likely pathogenic for mucopolysaccharidosis type VI in a recessive manner.
