P4HB encodes protein disulfide isomerase (PDI) and is identified as a novel candidate gene of OI. The purposes of the present study are to detect pathogenic mutation, to evaluate the phenotypes of a Chinese family with mild OI, and to investigate the effects of bisphosphonates on bone of the proband. We detected the pathogenic mutation by next generation sequencing and Sanger sequencing. Laboratory and radiological investigations were conducted to evaluate the phenotypes. The proband was a 12-year-old girl with low BMD, history of recurrent non-traumatic fractures, slight scoliosis, with bluish grey sclera and ligamentous laxity. Her father suffered from one fragility fracture and slight wedge changes of vertebras, with bluish grey sclera. We identified a novel heterozygous missense mutation (c.692A&amp;gt;C, p.His231Pro) in P4HB in the proband and her father. This mutation was predicted to affect the combination of PDI with type I procollagen and lead to the disorder of its triple helix formation. Bisphosphonates were effective in reducing bone resorption and increasing BMD of the proband with well tolerance. In conclusion, we identified a novel mutation in P4HB in a Chinese family with mild OI, which expanded the genotypic and phenotypic spectrum of OI. Bisphosphonates were effective to this extremely rare OI induced by P4HB mutation.<\/jats:p>","DOI":"10.1042\/bsr20182118","type":"journal-article","created":{"date-parts":[[2019,4,4]],"date-time":"2019-04-04T15:55:39Z","timestamp":1554393339000},"update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A novel missense mutation in <i>P4HB<\/i> causes mild osteogenesis imperfecta"],"prefix":"10.1042","volume":"39","author":[{"given":"Lujiao","family":"Li","sequence":"first","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dichen","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenbin","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ou","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weibo","family":"Xia","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoping","family":"Xing","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4380-3511","authenticated-orcid":false,"given":"Mei","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, National Health Commission Key Laboratory of Endocrinology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"288","published-online":{"date-parts":[[2019,4,30]]},"reference":[{"key":"2021111619273567700_B1","doi-asserted-by":"publisher","first-page":"1657","DOI":"10.1016\/S0140-6736(15)00728-X","article-title":"Osteogenesis imperfecta","volume":"387","author":"Forlino","year":"2016","journal-title":"Lancet"},{"key":"2021111619273567700_B2","doi-asserted-by":"publisher","first-page":"17052","DOI":"10.1038\/nrdp.2017.52","article-title":"Osteogenesis imperfecta","volume":"3","author":"Marini","year":"2017","journal-title":"Nat.
