Abstract

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.
