Severe cases usually require emergency care at birth. However, early diagnosis is often precluded by the rarity and consequent low awareness of this disease. This study aimed to clarify phenotypic expressions useful for the diagnosis of PS. We reviewed all cases of PS type 2 or 3 according to Cohen's classification that were reported between 1980 and 2011 in Japan. Clinical and genetic information were extracted from the patients' medical records. A total of 23 patients with PS type 2 or 3 were identified. All 23 patients presented with craniosynostosis, midface hypoplasia, proptosis, broad thumbs, and wide great toes. <jats:italic>FGFR2<\/jats:italic> mutations were confirmed in all 8 patients in whom genetic analyses were performed. In addition to classic symptoms, elbow ankylosis and sacrococcygeal defects were present in 70% and 30% of the patients, respectively. During an average follow\u2010up of 22 months, 22% of patients died before 1 year of age. Elbow ankylosis and sacrococcygeal defects were the phenotypic features recognizable at a glance. These defects strongly suggest the presence of PS in newborns with craniosynostosis. \u00a9 2012 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.35590","type":"journal-article","created":{"date-parts":[[2012,9,10]],"date-time":"2012-09-10T20:21:31Z","timestamp":1347308491000},"page":"2506-2510","source":"Crossref","is-referenced-by-count":11,"title":["Clinical expression in Pfeiffer syndrome type 2 and 3: Surveillance in Japan"],"prefix":"10.1002","volume":"158A","author":[{"given":"Hiroshi","family":"Koga","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naohiro","family":"Suga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takato","family":"Nakamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichi","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noboru","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,9,10]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001665-199805000-00002"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320450305"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0046-8177(84)80079-9"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0b013e3181a2057e"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19980724)78:4<356::AID-AJMG10>3.0.CO;2-H"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1399-0004.1994.tb04182.x"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.130.11.1298"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1159\/000089297"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00447500"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19980123)75:3<245::AID-AJMG3>3.0.CO;2-P"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng0994-98"},{"key":"e_1_2_6_13_1","unstructured":"RobinNH FalkMJ Haldeman\u2010EnglertCR.2011.FGFR\u2010related craniosynostosis syndromes.
