Affected individuals usually present with skeletal abnormalities such as metatarsal hypoplasia of the third and fourth toes and early\u2010onset arthropathy, as well as hearing loss. To date, no ophthalmic findings have been reported in patients with Czech dysplasia even though <jats:italic>COL2A1<\/jats:italic> has been implicated in other ocular conditions such as type 1 Stickler syndrome. For the first time, we report the ocular findings in four families with Czech dysplasia, including type 1 vitreous anomaly, hypoplastic vitreous, retinal tears, and significant refractive error. These novel ocular findings expand the phenotype associated with Czech dysplasia and may aid clinicians as an additional diagnostic feature. Patients with congenital abnormalities of vitreous gel architecture have an increased risk of retinal detachment, and as such, patients may benefit from prophylaxis. Considering that many of the patients did not report any ocular symptoms, vitreous phenotyping is of key importance in identifying the need for counseling with regard to prophylaxis.<\/jats:p>","DOI":"10.1002\/ajmg.a.63480","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T06:27:19Z","timestamp":1700461639000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ophthalmic manifestations of Czech dysplasia"],"prefix":"10.1002","volume":"194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4226-6005","authenticated-orcid":false,"given":"Zack","family":"Soh","sequence":"first","affiliation":[{"name":"Vitreoretinal Research Group, John van Geest Centre for Brain Repair University of Cambridge  Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Howard","family":"Martin","sequence":"additional","affiliation":[{"name":"Vitreoretinal Research Group, John van Geest Centre for Brain Repair University of Cambridge  Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Allan J.","family":"Richards","sequence":"additional","affiliation":[{"name":"Vitreoretinal Research Group, John van Geest Centre for Brain Repair University of Cambridge  Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohnish","family":"Suri","sequence":"additional","affiliation":[{"name":"Nottingham Clinical Genetics Service Nottingham University Hospitals NHS Trust  Nottingham UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0042-8659","authenticated-orcid":false,"given":"Martin P.","family":"Snead","sequence":"additional","affiliation":[{"name":"Vitreoretinal Research Group, John van Geest Centre for Brain Repair University of Cambridge  Cambridge UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,11,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMc2211320"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/genes13071150"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2007.03.059"},{"issue":"2","key":"e_1_2_7_5_1","first-page":"255","article-title":"Type II procollagen gene (COL2A1) mutation in exon 11 associated with spondyloepiphyseal dysplasia, tall stature and precocious osteoarthritis","volume":"22","author":"Bleasel J.
