Hunter syndrome (Mucopolysaccharidosis type II, MPS2) is an X-linked recessively inherited disease caused by a deficiency of iduronate 2 sulfatase (IDS). In this study, we investigated mutations of the IDS gene in 25 Korean Hunter syndrome patients. We identified 20 mutations, of which 13 mutations are novel; 6 small deletions (69_88delCCTCGGATCCGAAACGCAGG, 121-123delCTC, 500delA, 877_878delCA, 787delG, 1042_1049delTACAGCAA), 2 insertions (21_22insG, 683_684insC), 2 terminations (529G>T, 637A>T), and 3 missense mutations (353C>A, 779T>C, 899G>T). Moreover, using TaqI or HindIII RFLPs, we found three gene deletions. When the 20 mutations were depicted in a 3-dimensional model of IDS protein, most of the mutations were found to be at structurally critical points that could interfere with refolding of the protein, although they were located in peripheral areas. We hope that these findings will further the understanding of the underlying mechanisms associated with the disease.
