Two patients with a complete deletion of the iduronate-2-sulphatase (IDS) gene are described. In both patients, the resulting phenotype was that of very severe Hunter syndrome (mucopolysaccharidosis II). In addition, both had features not commonly seen in this disorder, e.g. early onset of seizures in one patient and ptosis in the other. It is speculated that loss of adjacent loci may contribute to the unusual findings and that the severe features present in both patients may represent contiguous gene syndromes. Further analysis of IDS cDNA from other patients with Hunter's syndrome may eventually enable phenotype to be predicted more accurately.

D007066 Iduronate Sulfatase An enzyme that specifically cleaves the ester sulfate of iduronic acid. Its deficiency has been demonstrated in Hunter's syndrome, which is characterized by an excess of dermatan sulfate and heparan sulfate. EC 3.1.6.13.

D016532 Mucopolysaccharidosis II Systemic lysosomal storage disease marked by progressive physical deterioration and caused by a deficiency of L-sulfoiduronate sulfatase. This disease differs from MUCOPOLYSACCHARIDOSIS I by slower progression, lack of corneal clouding, and X-linked rather than autosomal recessive inheritance. The mild form produces near-normal intelligence and life span. The severe form usually causes death by age 15.
