Mutations in the gene encoding the enzyme iduronate-2-sulfatase (IDS) were reported as the cause of the X-linked recessive lysosomal disease, mucopolysaccharidosis II (MPS II).
Hunter syndrome (Mucopolysaccharidosis type II) is a rare X-linked recessive lysosomal storage disorder caused by the deficiency of the enzyme iduronate-2-sulfatase (IDS).
Mucopolysaccharidosis type II (Hunter syndrome; OMIM 309900) is a rare X-linked recessive lysosomal storage disorder caused by the deficiency of the enzyme iduronate-2-sulfatase (IDS; EC 3.1.6.13).
Mutation analysis of iduronate-2-sulphatase gene in 24 patients with Hunter syndrome: characterisation of 6 novel mutations. Mutation in brief no. 249. Online.
We sequenced genomic DNA and RT-PCR products in the iduronate sulfatase (IDS) gene in 6 unrelated patients with Hunter syndrome to assess genotype/phenotype relationships and offer carrier testing where required.
Mucopolysaccharidosis type II (Hunter syndrome) is an X linked lysosomal storage disorder resulting from heterogeneous mutations in the iduronate-2-sulphatase (IDS) gene.
Hunter disease (mucopolysaccharidosis type II or MPS II) is an X-linked recessive disorder caused by the deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS) (E.C.3.1.6.13.) involved in the catabolism of mucopolysaccharides dermatan sulfate and heparan sulfate.
We have performed a molecular and mutation analysis of a total 19 unrelated MPS II patients of different ethnic origin and identified 19 different IDS mutations, 9 of which were novel and unique.
Our series of studies on Hunter disease in Japanese patients showed allelic heterogeneity of IDS gene mutations, genotype/phenotype correlation and racial differences in distribution of mutations.
