Although well documented in cattle, to date only seven human cases have been recorded, most of them aged under 2 years. We document the natural history of three patients with EDS dermatosparaxis type, two of whom have been reported before the age of 2 years, and one new patient. The phenotype of the patients, and especially the facial resemblance, is striking, making this a clinically recognizable condition. The most consistent anomalies during the first years of life are premature rupture of the membranes, extreme skin fragility and easy bruising, large fontanels, blue sclerae, puffy eyelids, micrognathia, umbilical hernia, and short fingers. Joint hypermobility becomes more important with age. The children are at risk for rupture of internal organs due to soft tissue fragility, as is illustrated by different internal events in two of the three patients described here. Orofacial features include micrognathia, a frontal open bite, and gingival hyperplasia with varying degrees of hyperkeratosis. The deciduous dentition shows abnormal morphology of the molars, obliteration of the tooth pulp, and severe enamel attrition. The permanent dentition shows agenesis and microdontia of several teeth. Tooth discoloration, dysplastic roots, and tooth pulp obliteration are present in a restricted number of permanent teeth. \u00a9 2004 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.30299","type":"journal-article","created":{"date-parts":[[2004,9,14]],"date-time":"2004-09-14T08:16:57Z","timestamp":1095149817000},"page":"18-28","source":"Crossref","is-referenced-by-count":75,"title":["The natural history, including orofacial features of three patients with Ehlers\u2013Danlos syndrome, dermatosparaxis type (EDS type VIIC)"],"prefix":"10.1002","volume":"131A","author":[{"given":"Fransiska","family":"Malfait","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"De Coster","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingrid","family":"Hausser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthonie J.","family":"van Essen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Franck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alain","family":"Colige","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Betty","family":"Nusgens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc","family":"Martens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne","family":"De Paepe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,9,7]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19980428)77:1<31::AID-AJMG8>3.0.CO;2-O"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.6.2374"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1086\/302504"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.0022-202X.2004.23406.x"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0714.2003.00170.x"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19970110)68:1<25::AID-AJMG5>3.0.CO;2-X"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3913(05)80355-5"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/BF03547060"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/1523-1747.ep12520000"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1042\/bj3550271"},{"key":"e_1_2_6_12_1","first-page":"115","article-title":"Dental findings in osteogenesis imperfecta: I.
