Through recent discoveries in the field of genetics, numerous genotypic variants have been implicated in pathologic skeletal phenotypes and disorders arising from the disturbance of one or more of these processes. For example, total loss-of-function variants of LRP5 were found to be the cause of osteoporosis-pseudoglioma syndrome (OPPG). LRP5 encodes for the low-density lipoprotein receptor-related protein 5, a co-receptor in the canonical WNT\u2013\u03b2-catenin signaling pathway and a crucial protein involved in the formation and maintenance of homeostasis of the human skeleton. Beyond OPPG, other partial loss-of-function variants of LRP5 have been found to be associated with other low bone mass phenotypes and disorders, while LRP5 gain-of-function variants have been implicated in high bone mass phenotypes. This review introduces the roles that LRP5 plays in skeletal morphogenesis and discusses some of the structural consequences that result from abnormalities in LRP5. A greater understanding of how the LRP5 receptor functions in bone and other body tissues could provide insights into a variety of pathologies and their potential treatments, from osteoporosis and a variety of skeletal abnormalities to congenital disorders that can lead to lifelong disabilities.<\/jats:p>","DOI":"10.3390\/genes14101846","type":"journal-article","created":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T10:40:22Z","timestamp":1695552022000},"page":"1846","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["LRP5, Bone Mass Polymorphisms and Skeletal Disorders"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7122-2423","authenticated-orcid":false,"given":"Jake","family":"Littman","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Warren Alpert Medical School of Brown University, Providence, RI 02903, USA"},{"name":"School of Medicine, University of Pittsburgh, Pittsburgh, PA 15261, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2127-6239","authenticated-orcid":false,"given":"Wentian","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Warren Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2391-5185","authenticated-orcid":false,"given":"Jon","family":"Olansen","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Warren Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chanika","family":"Phornphutkul","sequence":"additional","affiliation":[{"name":"Division of Human Genetics, Department of Pediatrics, Hasbro Children\u2019s Hospital, Warren Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0745-2267","authenticated-orcid":false,"given":"Roy K.","family":"Aaron","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Warren Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,23]]},"reference":[{"key":"ref_1","unstructured":"(2023, May 30).
