To date, more than 200 different mutations have been reported in the IDS gene, located on Xq27.3\u2013q28. Here, we report two new mutations (M488I and G489A) identified in hemizygosity in an Italian Hunter patient. Their \u201cin vitro\u201d expression by COS 7 cells was carried out in order to evaluate their functional consequence on enzyme activity as well as their possible cumulative effect on the malfunctioning of the protein. The results obtained enabled us to confirm the G489A mutation as causative. The M488I mutation, however, could not be unequivocally considered as causing disease because of its residual activity. Although a cumulative effect of the two mutations can be excluded \u201cin vitro,\u201d we are cautious about drawing a conclusion with regard to the possible role that the two mutations could have played \u201cin vivo\u201d in modulating the phenotype of the patient. Finally, the knowledge of the molecular defect of the patient has enabled us to identify the carriers, providing reliable genetic counselling to the females of the family. \u00a9 2003 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.10215","type":"journal-article","created":{"date-parts":[[2003,6,4]],"date-time":"2003-06-04T10:07:08Z","timestamp":1054721228000},"page":"84-87","source":"Crossref","is-referenced-by-count":13,"title":["Expression studies of two novel in CIS\u2010mutations identified in an intermediate case of Hunter syndrome"],"prefix":"10.1002","volume":"120A","author":[{"given":"Verena","family":"Ricci","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mirella","family":"Filocamo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefano","family":"Regis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Corsolini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marina","family":"Stroppiano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco Di","family":"Duca","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosanna","family":"Gatti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2003,1,8]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4439(01)00075-8"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1006\/geno.1993.1259"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0003-2697(92)90280-K"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/2.1.5"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(19)52451-6"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1042\/bj3260243"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4439(97)00096-3"},{"key":"e_1_2_6_9_1","first-page":"2465","volume-title":"The metabolic and molecular bases of inherited disease","author":"Neufeld EF","year":"1995"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0378-1119(91)90434-D"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0168-9525(99)01761-8"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.1380060206"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1101\/gr.5.1.71"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4439(00)00006-5"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1012763026526"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.87.21.8531"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1006\/geno.1993.1406"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.a.10215","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.10215","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,16]],"date-time":"2023-11-16T21:40:32Z","timestamp":1700170832000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.10215"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,1,8]]},"references-count":16,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2003,7]]}},"alternative-id":["10.1002\/ajmg.a.10215"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.10215","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,1,8]]}}}
