We report a Chinese boy with brachyolmia caused by a novel compound heterozygous mutation in the <jats:italic>PAPSS2<\/jats:italic> gene. Prenatal ultrasound revealed shortened long bones, and his birth length was markedly reduced (45\u2009cm, \u22123.11 SD). Clinical and radiographic findings were consistent with brachyolmia, and genetic analysis confirmed the diagnosis of BCYM4 at 2\u2009years and 9 months old. During follow\u2010up, the patient exhibited progressive growth retardation. Under pediatric orthopedics supervision, growth hormone (GH) therapy was initiated to ameliorate his short stature since 5\u2009years and 6 months old. Over a 2\u2010year and 3\u2010month treatment period, GH therapy significantly improved his growth velocity, with his height increasing from \u22125.02 SD to \u22123.87 SD. Notably, severe growth restriction was evident as early as 25\u2009weeks' gestation, and spinal radiographs demonstrated persistent skeletal abnormalities. This case expands the phenotypic spectrum of BCYM4 and provides evidence supporting the efficacy of GH therapy in improving growth outcomes in patients with skeletal dysplasia\u2010associated short stature.<\/jats:p>","DOI":"10.1002\/ccr3.70788","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T03:45:53Z","timestamp":1757303153000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["PAPSS2\u2010Related Brachyolmia: Clinical and Radiographic Features and Growth Hormone Therapy of One Chinese Case"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-2889-0910","authenticated-orcid":false,"given":"Wenjun","family":"Long","sequence":"first","affiliation":[{"name":"Department of Pediatrics Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoping","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,7]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19980806)78:5<468::AID-AJMG13>3.0.CO;2-D"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/humu.22377"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.35906"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.61282"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.2000.2123"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmedgenet-2012-101039"},{"key":"e_1_2_14_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-016-2458-8"},{"key":"e_1_2_14_9_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0810489"},{"key":"e_1_2_14_10_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2014-3556"},{"key":"e_1_2_14_11_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0059569"},{"key":"e_1_2_14_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/gim.2015.30"},{"key":"e_1_2_14_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/mgg3.1916"},{"key":"e_1_2_14_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/dvdy.21137"},{"key":"e_1_2_14_15_1","doi-asserted-by":"publisher","DOI":"10.1515\/jpem-2020-0393"},{"key":"e_1_2_14_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00774-003-0425-7"},{"key":"e_1_2_14_17_1","first-page":"439","article-title":"Idiopathic Short Stature and Scoliosis in Children Treated With Growth Hormone","volume":"105","author":"Hong H.","year":"2023","journal-title":"Bone & Joint Journal"}],"container-title":["Clinical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccr3.70788","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,30]],"date-time":"2025-09-30T03:55:54Z","timestamp":1759204554000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccr3.70788"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,9]]},"references-count":16,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2025,9]]}},"alternative-id":["10.1002\/ccr3.70788"],"URL":"https:\/\/doi.org\/10.1002\/ccr3.70788","archive":["Portico"],"relation":{},"ISSN":["2050-0904","2050-0904"],"issn-type":[{"value":"2050-0904","type":"print"},{"value":"2050-0904","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,9]]},"assertion":[{"value":"2024-10-14","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-04-02","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-07","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70788"}}
