Genes affected

IDS (HGNC:5389): (iduronate 2-sulfatase) This gene encodes a member of the sulfatase family of proteins. The encoded preproprotein is proteolytically processed to generate two polypeptide chains. This enzyme is involved in the lysosomal degradation of heparan sulfate and dermatan sulfate. Mutations in this gene are associated with the X-linked lysosomal storage disease mucopolysaccharidosis type II, also known as Hunter syndrome. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed. [provided by RefSeq, Jan 2016]

ClinVar contains an entry for this variant (Variation ID: 10486). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. For these reasons, this variant has been classified as Pathogenic. This premature translational stop signal has been observed in individuals with mucopolysaccharidosis II (PMID: 1303211, 18500569, 21291454, 21829674, 27146977). This sequence change creates a premature translational stop signal (p.Arg443*) in the IDS gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 108 amino acid(s) of the IDS protein. This variant is not present in population databases (gnomAD no frequency). -
