SEDC is usually caused by substitution of glycine residue with another amino acid in the triple helical domains of alpha 1 chains, which consist of type II collagen (<jats:italic>COL2A1<\/jats:italic>). Herein, we describe a unique case of SEDC with mild coxa vara (SEDC\u2010M) caused by double de novo <jats:italic>COL2A1<\/jats:italic> mutations located on the same allele. One mutation, p.G504S, was previously described in patients with SEDC, whereas the other, p.G612A, was a novel mutation; both were located in the triple helical domain. Neither mutation was identified in the parents and appeared to be de novo. To the best of our knowledge, this is the first study involving a patient with a type II collagenopathy with two <jats:italic>COL2A1<\/jats:italic> mutations on the same allele. The case was characterized by a more severe phenotype compared with previously reported cases involving a single p.G504S mutation, which may have been the result of the double mutation. \u00a9 2015 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajmg.a.37073","type":"journal-article","created":{"date-parts":[[2015,4,22]],"date-time":"2015-04-22T03:50:58Z","timestamp":1429674658000},"page":"1578-1581","source":"Crossref","is-referenced-by-count":4,"title":["Spondyloepiphyseal dysplasia congenita caused by double heterozygous mutations in <i>COL2A1<\/i>"],"prefix":"10.1002","volume":"167","author":[{"given":"Osamu","family":"Kawano","sequence":"first","affiliation":[{"name":"Department of Pediatrics Obihiro Kyokai Hospital Obihiro Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akie","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Hokkaido University School of Medicine Kita\u2010ku Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuntaro","family":"Morikawa","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Hokkaido University School of Medicine Kita\u2010ku Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kimiaki","family":"Uetake","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Obihiro Kousei Hospital Obihiro Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsura","family":"Ishizu","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Hokkaido University School of Medicine Kita\u2010ku Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiro","family":"Tajima","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Hokkaido University School of Medicine Kita\u2010ku Sapporo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,4,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth0410-248"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.4238\/2012.September.27.1"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0500267102"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1754.2010.01979.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.10147"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1038\/nprot.2009.86"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.12816\/0003199"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.20179"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.32880"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31084"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31556"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/4.7.1169"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01959208"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng0995-87"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.1380010510"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.64B4.6807992"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cca.2007.04.005"}],"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.37073","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.37073","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T15:49:54Z","timestamp":1696607394000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.37073"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,4,21]]},"references-count":17,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2015,7]]}},"alternative-id":["10.1002\/ajmg.a.37073"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.37073","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,4,21]]}}}
