Three major clinical forms have been established: type I (infantile), type II (late infantile\/juvenile) and type III (adult). A mutational analysis was performed in 19 patients with GM1 gangliosidosis from South America, mainly from Argentina. Two of them were of Gypsy origin. Main clinical findings of the patients are presented. All 38 mutant alleles were identified: of the 22 different mutations found, 14 mutations are described here for the first time. Among the novel mutations, five deletions were found. Four of them are relatively small (c.435_440delTCT, c.845_846delC, c.1131_1145del15 and c.1706_1707delC), while the other one is a deletion of 1529 nucleotides that includes exon 5 and is caused by an unequal crossover between intronic <jats:italic>Alu <\/jats:italic>sequences. All the described patients with GM1 gangliosidosis were affected by the infantile form, except for four unrelated patients classified as type II, III, and II\/III (two cases). The two type II\/III patients bore the previously described p.R201H mutation, while the adult patient bore the new p.L155R. The juvenile patient bore two novel mutations: p.S434L and p.G554E. The two Gypsy patients are homozygous for the p.R59H mutation as are all Gypsy patients previously genotyped.<\/jats:p>","DOI":"10.1111\/j.1399-0004.2007.00767.x","type":"journal-article","created":{"date-parts":[[2007,2,19]],"date-time":"2007-02-19T12:49:04Z","timestamp":1171889344000},"page":"273-279","source":"Crossref","is-referenced-by-count":40,"title":["Identification of 14 novel <i>GLB1 <\/i>mutations, including five deletions, in 19 patients with GM1 gangliosidosis from South America"],"prefix":"10.1111","volume":"71","author":[{"given":"R","family":"Santamaria","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Blanco","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Chab\u00e1s","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Grinberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Vilageliu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,2,19]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"3775","volume-title":"The metabolic and molecular bases of inherited disease","author":"Suzuki Y","year":"2001"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01247344"},{"key":"e_1_2_6_4_2","doi-asserted-by":"crossref","first-page":"20655","DOI":"10.1016\/S0021-9258(19)47114-7","article-title":"Alternative splicing of beta\u2010galactosidase mRNA generates the classic lysosomal enzyme and a beta\u2010galactosidase\u2010related protein","volume":"264","author":"Morreau H","year":"1989","journal-title":"J Biol Chem"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00194225"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.273.11.6319"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/humu.20147"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-1004(200004)15:4<354::AID-HUMU8>3.0.CO;2-L"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-1004(1999)13:5<401::AID-HUMU9>3.0.CO;2-N"},{"key":"e_1_2_6_10_2","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1007\/s00439-003-0930-8","article-title":"Modulating action of the new polymorphism L436F detected in the GLB1 gene of a type\u2010II GM1 gangliosidosis patient","volume":"113","author":"Caciotti A","year":"2003","journal-title":"Hum Genet"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/humu.9451"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymgme.2005.12.009"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1006\/mgme.1999.2864"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1086\/302968"}],"container-title":["Clinical Genetics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1399-0004.2007.00767.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1399-0004.2007.00767.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,15]],"date-time":"2023-10-15T22:50:09Z","timestamp":1697410209000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1399-0004.2007.00767.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,2,19]]},"references-count":13,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2007,3]]}},"alternative-id":["10.1111\/j.1399-0004.2007.00767.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1399-0004.2007.00767.x","archive":["Portico"],"relation":{},"ISSN":["0009-9163","1399-0004"],"issn-type":[{"value":"0009-9163","type":"print"},{"value":"1399-0004","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,2,19]]}}}
